I have a Google App Script program that has a number of HTML pages. To generate the URL's for links to individual pages, I use this function on the server code:
function getScriptUrl() {
var url = ScriptApp.getService().getUrl();
return url;
}
to return a URL that I could then embed like this, on the client side:
<?var myURL = getScriptUrl();?><a class="btn btn-success" href='<?=myURL?>?page=CreateNew'>My Button/a>
This always returned the URL of the app. So, if am testing in the Dev version, it returns the Dev URL, if I am in the Exe version, it returns the Exe URL. But, now, if I am in the Dev version, it returns the Exe URL. This was never an issue in the past but started today. Does anyone know why this is happening or a better way to generate the URL to create links between pages?
EDIT:
I have tried to republish the app (in Legacy Editor and the New Editor), log out of G Suite account, clear my cache but these attempts did not work to address the issue.
This should a Google part issue, I use the same logic to auto direct to prod and test page. It works fine in the passed few month. But it can't work from last week.
I too have this problem. Until recently I had this code to help me distinguish whether I was testing the development version or the deployed version. It worked for months.
const url = ScriptApp.getService().getUrl();
if (url.endsWith('dev')) {
// more code here
}
Now getUrl() will always return the exec url.
(I know this isn't an answer, but I am a first time poster and do not have enough points to "Add a comment" and I don't want to ask a duplicate question)

I am creating some google app scripts for my company to use to generate random tests for employee training. I already have the basic scripts written to grab a list of questions from a google sheet, randomize them, grab the first 10 questions, etc. That all works fine. I decided it might be better to re-do the whole thing using a UiApp instead of just separate scripts. That is where the problem comes in. I did a simple bare bones UiApp to test with, published it and tried to hit the URL and that's where I encounter this error. I searched for this error and all I could find was some discussion about this being part of google apps premiere(which should have been folded into regular google apps around 2010). I've been staring at this so long I've frustrated myself. It should be something very simple and yet it's refusing to work. I'm assuming I am doing something wrong at a basic level but I've reached the point where my brain refuses to see it.
Here is the basic script I started with:
function doGet(e) {
var app = UiApp.createApplication();
var mainPanel = app.createVerticalPanel().setId('mainPanel');
mainPanel.add(app.createLabel('test'));
return app;
}
I save it, publish it and go to the URL and that's when I get the above error message. I know it's something simple but I've reached the point of frustration and simply can't see it.
Update: to reflect comments
Another possibility for WebApps not updating is not publishing a new version and only checking the exec URL. For instant changes to the code, always check the dev URL. The exec will only change after saving a version in Manage Versions and re-publishing the app.
First Answer:
I think your question title says it all.
UIApp is not defined, but Class is UiApp. JS is case sensitive. I copied and pasted the code exactly as it is in your question and received no errors. I did have to add one line to make the label show up.
function doGet(e) {
var app = UiApp.createApplication();
var mainPanel = app.createVerticalPanel().setId('mainPanel');
mainPanel.add(app.createLabel('test'));
app.add(mainPanel); // <-- I added this line to see the label
return app;
}
When executing a script directly in the console in Chrome, I saw this:
Does anyone know what's the meaning of VM117:2
What does VM stand for ?
It is abbreviation of the phrase Virtual Machine.
In the Chrome JavaScript engine (called V8) each script has its own script ID.
Sometimes V8 has no information about the file name of a script, for example in the case of an eval. So devtools uses the text "VM" concatenated with the script ID as a title for these scripts.
Some sites may fetch many pieces of JavaScript code via XHR and eval it. If a developer wants to see the actual script name for these scripts she can use sourceURL. DevTools parses and uses it for titles, mapping etc.
Thanks to #MRB,
I revisited this problem, and found the solution today,
thanks to https://stackoverflow.com/a/63221101/1818089
queueMicrotask (console.log.bind (console, "Look! No source file info..."));
It will group similar elements, so make sure you add a unique identifier to each log line to be able to see all data.
Demonstrated in the following example.
Instead of
data = ["Apple","Mango","Grapes"];
for(i=0;i<10;i++){
queueMicrotask (console.log.bind (console, " info..."+i));
}
use
data = ["Apple","Mango","Grapes"];
for(i=0;i<data.length;i++){
queueMicrotask (console.log.bind (console, " info..."+i));
}
A better way would be to make a console.print function that does so and call it instead of console.log as pointed out in https://stackoverflow.com/a/64444083/1818089
// console.print: console.log without filename/line number
console.print = function (...args) {
queueMicrotask (console.log.bind (console, ...args));
}
Beware of the grouping problem mentioned above.
Good Evening!
I've been looking into the possibility of using GAS(Google Apps Script) to host a small bit of javascript that lets me use the new Google finance apps api. The intention being that I'll be using the stock information for a project which involves the use of stock data. I know that there are a few ways to get stock information from Google, but the data that the finanace app returns is more in-line with other sources we are using. (One constraint on this project is that we have multiple sources).
I've written the javascript and I can call a httpc:request to the URL for the script given to me from Google. In the browser the JS returns the json object as I want it, however when the call is made from Erlang I'm getting it in a list of ascii. From checking the values it appears to be a document starting like:
Below is the javascript and the url to see the json:
https://script.google.com/macros/s/AKfycbzEvuuQl4jkrbPCz7hf9Zv4nvIOzqAkBxL1ixslLBxmSEhksQM/exec
function doGet() {
var stock = FinanceApp.getStockInfo('LON:TSCO');
return ContentService.createTextOutput(JSON.stringify(stock))
.setMimeType(ContentService.MimeType.JSON);
}
For the erlang, it's a simple request but I've not been doing erlang long, so perhaps I've messed something up here (The URL being the one mentioned above). I've got crypto / ssl / inets when I'm testing this on the command line.
{ok, {Version, Headers, Body}} = httpc:request(get, URL, []}, [], []).
I think it's also worth mentioning that when i curl it from Cygwin, I get a massive load of HTML also, I've included it below, but if you see it you'll thank me for not posting it in here! http://pastebin.com/UtJHXjRm
I've been updating the script as I go with the new versions but I'm at a bit of a loss as to why it's not returning correctly.
If anyone can give me any pointers I'd be very grateful! I get the feeling that it's not intended to be used this way, perhaps only within other Google products and such.
Cheers!
It would be necessary to review how are you deploying the Web App, specifically the Who has access to the app, to access without authentication should be configured as shown in the image:
See Deploying Your Script as a Web App from the documentation.
In my test, by running:
curl -L https://script.google.com/macros/s/************/exec
Get the following result:

Possibly your GET is not following the REDIRECT that happens when you use contentService. Look at the html returned there is a redirect in there.
I can't seem to access URL parameters in my simple webapp. From the documentation it looks very simple:
function doGet(e) {
var foo = (e.parameters.test);
return ContentService.createTextOutput("Test: " + foo);
}
But foo keeps coming back as "undefined" when I run the webapp, either using the "my latest code" developer link, or a deployed version.
I've also noticed that when the page loads the URL Parameters I tack on at the end disappear.
The URL looks like:
https://script.googleusercontent.com/a/macros/mysite.com/echo?user_content_key=superlongstring&lib=otherstring&test=helloworld
You should tack on the parameter before the script URL redirects.
So it should look like -
https://script.google.com/macros/s/longstring/exec?test=helloworld
The redirected URL is really only for the output and its not re-usable and it wont trigger any new processing.
Is there a Chrome extension post install hook/API function that will let me perform an action after the plugin is installed or updated?
I would like to perform an action after my extension is installed, and only right after it is installed. This action should only be performed once (post-install or post-update) of the extension.
Update
Some people have proposed setting the version of the extension in localStorage, the problem that I have is that the content script that has access to localStorage is not loaded into the page when the plugin is first installed.
AFAIK after a plugin is installed, and it makes use of a content script injected into the tab/page, the page has to be reloaded.
I don't know how to access localStorage from the background page; localStorage can only be accessed from a content script.
To get the version number from the background page to the content script requires the use of chrome API function to execute scripts:
chrome.tabs.executeScript(null, {code:function_to_execute}, function() { // callback });
However, when you install a plugin, and the page that this plugin needs to inject a content script into is already loaded, it does not inject the content script, you have to reload the page.
update 2
Looking at some of the tips provided in more detail, for the purpose of saving the version number, it is possible to access the localStorage of the background page. However, for what I need to do, which is reload a specific tab at a specific URL (in order to make sure the content script is the newest version) after installing or updating a plugin, it ended up being unnecessary to bother with localStorage.
For the sake of staying on topic, the advice given about writing the version number to localStorage (in the background page) and then checking against the version number in the manifest file is good enough to allow someone to run a script the first time it is installed/or updated.
HowTo
Make manifest file available to the background page (note: this is taken from somewhere else, I don't take credit for it, but I can't remember the source, if you know, let me know and I will add it).
// MAKE MANIFEST FILE AVAILABLE
chrome.manifest = (function() {
var manifestObject = false;
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
manifestObject = JSON.parse(xhr.responseText);
}
};
xhr.open("GET", chrome.extension.getURL('/manifest.json'), false);
try {
xhr.send();
} catch(e) {
console.log('Couldn\'t load manifest.json');
}
return manifestObject;
})();
Now you can access your version number like this: chrome.manifest.version
To write to localStorage just pass it in like so: localStorage['my_plugin_version'] = chrome.manifest.version
You can do this using a background page. When the extension is installed, the background page is opened in the background, and thus executed. To make sure it's not executed every time, simply store a value in localStorage.
