Google App Script not firing every time onedit trigger is used - google-apps-script

Question

Google App script not firing all JavaScript pop up boxes using on edit trigger. Does not fire when a change is made to the sheet for multiple users. Also only works when it feels like it. I have set the trigger to onEdit(). My code:
function Error() {
var sheet = SpreadsheetApp.getActiveSheet();
if (sheet.getName() == "Protocal Check List 2"){
var ui = SpreadsheetApp.getUi(); // Same variations.
var ss = SpreadsheetApp.getActiveSpreadsheet();
var active = ss.getActiveCell();
var getactive = ss.getActiveCell().getDisplayValue();
var column = ss.getActiveRange().getColumn();
var row = ss.getActiveRange().getRow();
var msg = '';
var section = sheet.getRange('C'+ row);
switch (column) {
case 9:
var msg = "error 1";
break;
case 10:
var msg = "Error 2";
break;
default:
msg = "Error";
break;
}
if(getactive == "TRUE"){
if(column >= 9 && column <= 60
){
var result = ui.alert(
"pika Says",
msg,
ui.ButtonSet.YES_NO);
// Process the user's response.
if (result == ui.Button.YES) {
// User clicked "Yes".
window.alert('Task Complete: \n\n' + msg);
active.setValue('True');
} else {
var i = 0;
while (i < 1) {
var result = ui.prompt(
'Please detail cause of the problem:',
ui.ButtonSet.OK);
var text = result.getResponseText();
var textcount = text.length;
if(textcount > 0) {
i++;
}}
var cell = "H" + row;
var emailAddress = "email#gmail.com";
var d = new Date();
var n = d.toDateString();
var t = d.toTimeString();
var staffname = ss.getRange(cell).getValues();
var message = "Date: " + n +"\n\nTime: " + t +"\n\nStaff: " + staffname + "\n\nError: " + msg + "\n\nProblem: " + text;
var subject = msg;
var thedate = n + " / " + t;
ss.getRange('A1').setValue(thedate);
ss.getRange('B1').setValue(staffname);
ss.getRange('C1').setValue(msg);
ss.getRange('D1').setValue(text);
var s1 = ss.getRange('A1:D1'); //assign the range you want to copy
var s1v = s1.getValues();
var tss = SpreadsheetApp.openById('1mOzdRgKxiP5iB9j7PqUWKKo5oymWuAeQZ1jJ1s6qL9E'); //replace with destination ID
var ts = tss.getSheetByName('AB Protocal'); //replace with destination Sheet tab name
ts.getRange(ts.getLastRow()+1, 1, 1,4).setValues(s1v); //you will need to define the size of the copied data see getRange()
MailApp.sendEmail(emailAddress, subject, message);
// User clicked "No" or X in the title bar.
//ui.alert("The following note has been sent to the Duty Manager: \n\n" + text);
active.setValue('FALSE');
}}}}
}
Any help would be appreciated. I need it to run every signal time for users who have access to the sheet.

Answer 1

You'll have to
assume that onEdit triggers are best-effort, but may not catch all
edits done to the spreadsheet.
Bug thread is here.

Answer 2

To get around the bug as mentioned by Edward implemente a dumb router.
// create a new file -> router.gs
function routerOnEdit(e) {
myOnEditHook1(e);
myOnEditHook2(e);
myOnEditHook3(e);
}

I have submitted an issue, which is the updated version of a long-running 7 year issue. They closed it in 2022, saying the feature is intended. They have now added a feature where onEdit can queue up to 2 trigger events. The issue I'm having is that the second edit still does not trigger. Despite what the documentation says.
Note: The onEdit() trigger only queues up to 2 trigger events.
