The Google support article example under the Forms heading is broken. From the article:
If you call a server function with a form element as a parameter, the form becomes a single object with field names as keys and field values as values. The values are all converted to strings, except for the contents of file-input fields, which become Blob objects.
I tested this by passing a Form element containing 5 text inputs and a file, then logging Object.keys() on the form object. It returned only the 5 text fields, the file was stripped from the form object. Attempting to assign the file blob directly returned Exception: Invalid argument: blob
How do I pass the file blob from the client-side Form to the server-side Apps Script?
EDIT: To clarify, I also copy-pasted the example provided by Google verbatim. It errors with Exception: Invalid argument: blob.
To reproduce:
Create new Google Apps Script project

I can confirm that this doesn't work in G-Suite Enterprise. I don't know why because I cannot find documentation that says how Google is serializing the data. It could be a browser/computer security setting or something in G-Suite.
However, there is an easier way to accomplish your need. You can use a Google Form with a file upload question and then create an on form submit trigger/event on it to copy the file to a team/shared drive. Here is sample code if you want to attach the trigger to the Google Form itself:
// ID of the destnation folder to save the file in
var destinationFolderID = "10gkU_2V9iYy-VKudOCOjydEpoepPTgPv"
function saveFileToTeamDrive(e)
{
// a place to save the URL of the uploaded file
var fileID;
// go through all of the responses to find the URL of the uploaded file
e.response.getItemResponses().forEach(function(itemResponse){
// once we find the question with the file
if(itemResponse.getItem().getTitle() == "File Upload Test")
{
// get the file ID from the response
fileID = itemResponse.getResponse();
return;
}
});
// stop if we didn't have one
if(!fileID.length) return;
// get the first index in the array
fileID = fileID[0];
// get the file
var file = DriveApp.getFileById(fileID);
// get the destination folder
var destinationFolder = DriveApp.getFolderById(destinationFolderID);
// make a copy
var newFile = file.makeCopy(destinationFolder);
Logger.log(newFile.getUrl());
}
You can also attach to the on form submit event of a Google Sheet that is linked to a Google Form. I find that way easier cause the Google Sheet on form submit trigger/event includes a JSON of the question/answers so you don't have to iterate all of them to find it. It also means you can re-run a submission if it failed.
WARNING
One important note, if you do either of these things do not give anyone else edit access to the code. This is because as soon as you create and authorize the trigger, anyone who has edit access to the code would be able to use it to gain access to your Google Drive (and anything else the trigger is authorized for). Please see securing a Google Apps Script linked to an authorized trigger so others can edit for more information.

Issue and workaround:
On December 9, 2021, the file object got to be able to be parsed from the Javascript side to the Google Apps Script side with V8 runtime. But, in this case, this can be used for only Web Apps. In the current stage, the sidebar and dialog cannot parse the file object on the Javascript side. Ref I think that this is the reason of your issue. So, in the current stage, it is required to send the file object as the string and the byte array for the sidebar and the dialog.
In this case, in order to achieve your goal using the current workaround, I would like to propose the following 2 patterns.
By the way, I think that in your Google Apps Script, an error occurs at SpreadsheetApp.getActiveCell().setFormula( formula );. Because SpreadsheetApp has no method of getActiveCell(). In this case, I think that getActiveRange() might be suitable.
Modified script:
In this modification, the file object is converted to the byte array, and the data is sent to Google Apps Script side.
Google Apps Script side:
function showForm() {
var html = HtmlService.createHtmlOutputFromFile('index');
SpreadsheetApp.getUi().showModalDialog(html, 'Upload File');
}
function uploadFile(e) {
var blob = Utilities.newBlob(...e);
var upFile = DriveApp.getFolderById('*FolderID*').createFile(blob).setName(e[2]);
Logger.log(upFile);
var fileUrl = upFile.getUrl();
var formula = '=HYPERLINK("' + fileUrl + '","' + e[2] + '")';
SpreadsheetApp.getActiveRange().setFormula(formula);
return "Uploaded!";
}
HTML & Javascript side:

How do I convert jpg or png image to Blob via a Google Apps Script Web App?
I am testing the app script platform and I have a doubt when using this code called from HTML file:
JSON.parse(<?= JSON.stringify(getDataFromSheet("tyreUse", "valueSearched")); ?>);
If I set the string value directly it works.
If I try to pass a variable that is declared in it does not recognize it. How can I pass a JS variable to the app script function like next example?
let value_searched = "cars";
JSON.parse(<?= JSON.stringify(getDataFromSheet("tyreUse", value_searched)); ?>);
Scriptlets like <?= ?> are used in html templates to load data from the server into html pages prior to rendering. If you want to pass data back to a server side function then you can use google.script.run and there are restrictions on the data types that you can pass.
google.script.run
Here is an example of getting data from spreadsheet dynamically. I typically build my page and then use an anonymous function of the form (function () {}()); to get the data from spreadsheet and populate the HTML elements with the values.

The same problem when I tried a docx file. (Before upload: 45kb) (After upload: 79kb) (Error message#1: Word found unreadable content. Do you want to recover the contents of this document?)(After pressing Yes: Word experienced an error trying to open the file. Try these suggestions. Blablabla)

How can i submit a ui.prompt in Google Script bypressing "enter key" instead of clicking ok?
Code so far:
function PromptBox()

var spreadsheet = SpreadsheetApp.getActive();
var ui=SpreadsheetApp.getUi();
var prompt=ui.prompt("Filter op... ", "Geef je filterwoord op", ui.ButtonSet.OK)
var response=prompt.getResponseText();
var button=prompt.getSelectedButton();
var filterTekst = "";
if (button==ui.Button.OK)
{
return (filterTekst = response);
}
else if(button==ui.Button.CANCEL)
{
ui.alert("Je hebt geannuleerd");
}
}
Roll your own dialog/prompt
You can accomplish this by rolling your own dialog. This a templated html approach so you will have to create some files to implement it. It isn't necessary to do it this way. It happens to be easier for me because all of the css, resource and script files were already created and I find it easier to create the javascript in a file rather than in a string.
Google Script Code:
function showPromptResponse(title,prompt,placeholder){
var title=title || "Prompt Response";//default used for debug
var prompt=prompt || "Enter your Response";//default used for debug
var placeholder=placeholder || "This is the placeholder";//default used for debug
var html="";
html+='<!DOCTYPE html><html><head><base target="_top"><?!= include("res1") ?><?!= include("css1") ?></head><body>';
//html+='<body>';
html+=Utilities.formatString('<h1>%s</h1>', title);
html+=Utilities.formatString('<p>%s</p>',prompt);
html+=Utilities.formatString('<br /><input id="resptext" type="text" size="25" placeholder="%s" />',placeholder);
html+='<br /><input id="okbtn" type="button" value="Ok" onClick="getResponse();" />';
html+='<br /><input id="cancelbtn" type="button" value="Cancel" onClick="google.script.host.close();" />';
html+='<?!= include("promptscript") ?>';
html+='</body></html>';
var ui=HtmlService.createTemplate(html).evaluate();//This is a template
SpreadsheetApp.getUi().showModelessDialog(ui, 'My Prompt');//launch dialog here
}
function loadResponse(resptext) {//This function determines where response is loaded into the spreadsheet.
SpreadsheetApp.getActive().getActiveSheet().getRange('A1').setValue(resptext);
}
function include(filename){//used in the template for loading file content
return HtmlService.createHtmlOutputFromFile(filename).getContent();
}
Javascript in a file named promtscript.html
<script>
$(function(){
var input = document.getElementById("resptext");
input.addEventListener("keyup", function(event) {
event.preventDefault();//this isn't required since were not doing a submit but it doesn't seem to hurt anything so I left it.
if (event.keyCode === 13) {//this captures the return keypress
document.getElementById("okbtn").click();
}
});
});
function getResponse(){
var responseText=$('#resptext').val();
console.log(responseText);
if(responseText){
google.script.run.loadResponse(responseText);//send response to google script
}else{
alert('Invalid or No Response');//response if nothing entered
}
}

Client To Server Communication
Currently I've developed a Google Scripts API which is used for people to upload files to a shared Google Drive folder. After the file are uploaded successfully, I want them to be taken to a separate "Thank you" page so it is clear their upload has worked. Currently I only have a message on the same page to this effect and I cannot figure out how to direct to a new page that I have created.
This is the additional bit I found from different questions to try direct to a new page however this is not working so far, as it remains on the same upload form page. I have included it at the bottom of my code.gs file. Any ideas on how to direct to a custom page that just says "thank you" or something similar would be great!
function doPost(e) {
var template = HtmlService.createTemplateFromFile('Thanks.html');
return template.evaluate();
}
The rest of my code is as follows:

HtmlService.SandboxMode.IFRAME);
}
function createFolder(parentFolderId, folderName) {
try {
var parentFolder = DriveApp.getFolderById(parentFolderId);
var folders = parentFolder.getFoldersByName(folderName);
var folder;
if (folders.hasNext()) {
folder = folders.next();
} else {
folder = parentFolder.createFolder(folderName);
}
return {
'folderId' : folder.getId()
}
} catch (e) {
return {
'error' : e.toString()
}
}
}
function uploadFile(base64Data, fileName, folderId) {
try {
var splitBase = base64Data.split(','), type = splitBase[0].split(';')[0]
.replace('data:', '');
var byteCharacters = Utilities.base64Decode(splitBase[1]);
var ss = Utilities.newBlob(byteCharacters, type);
ss.setName(fileName);
var folder = DriveApp.getFolderById(folderId);
var files = folder.getFilesByName(fileName);
var file;
while (files.hasNext()) {
// delete existing files with the same name.
file = files.next();
folder.removeFile(file);
}
file = folder.createFile(ss);
return {
'folderId' : folderId,
'fileName' : file.getName()
};
} catch (e) {
return {
'error' : e.toString()
};
}

Thank you for submitting!

EDIT:
I have changed this function as recommended:
if (numUploads.done == numUploads.total) {
window.location = 'Thanks.html';
numUploads.done = 0;
Now it is redirecting to another page but I am faced with this error:
That’s an error.
The requested URL was not found on this server. That’s all we know.
If you are looking for the solution of your issue yet, how about this answer?
You want to open Thanks.html when the process at Form.html is finished.
Form.html and Thanks.html are put in a project.
If my understanding is correct, how about this workaround? I have ever experienced with your situation. At that time, I could resolve this issue by this workaround.
Modification points:
It is not required to use doPost() to access to Thanks.html. I think that you can achieve what you want using doGet().
I think that #Scott Craig's answer can be also used for this situation. In my workaround, the URL of window.location = 'Thanks.html'; is modified.
Uses the URL of deployed Web Apps. In your script, when users access to your form, they access to the URL of the deployed Web Apps. In this workaround, it is used by adding a query parameter.
Modified scripts:
Form.html
For the script added in your question as "EDIT", please modify as follows.
From:
window.location = 'Thanks.html';
To:
window.location = 'https://script.google.com/macros/s/#####/exec?toThanks=true';
https://script.google.com/macros/s/#####/exec is the URL of the the deployed Web Apps. Please add a query parameter like toThanks=true. This is a sample query parameter.
Code.gs
Please modify doGet() as follows.
From:
function doGet() {
return HtmlService.createHtmlOutputFromFile('form')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
To:
function doGet(e) {
if (e.parameter.toThanks) {
return HtmlService.createHtmlOutputFromFile('Thanks')
.setSandboxMode(HtmlService.SandboxMode.IFRAME)
.setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);
} else {
return HtmlService.createHtmlOutputFromFile('form')
.setSandboxMode(HtmlService.SandboxMode.IFRAME);
}
}
Note:
When the script of the deployed Web Apps was modified, please redeploy it as new version. By this, the latest script is reflected to Web Apps.
The flow of this modified script is as follows.
When users access to the Form.html, because the query parameter of toThanks=true is not used, Form.html is returned.
When onFileUploaded() is run and if (numUploads.done == numUploads.total) {} is true, it opens the Web Apps URL with the query parameter of toThanks=true. By this, if (e.parameter.toThanks) {} of doGet() is true, and Thanks.html is returned and opened it.
In my environment, I could confirm that this modified script worked. But if this didn't work in your environment, I'm sorry. At that time, I would like to think of about the issue.
I might be misunderstanding your question, but from what I understand, instead of this line:
document.getElementById('output').innerHTML = 'All of the '
+ numUploads.total + ' files are uploaded';
You want to redirect to Thanks.html. If that's correct, just replace the above line with:
window.location = 'Thanks.html';
