onEdit function update undo history - google-apps-script

Question

I need to store the last modification user and date of a sheet in developer metadata.
I use the onEdit function to update these metadata at each edit of a sheet (please see the code below)
My problem is the metadata creation/update is taken into account in the undo history.
So users need to ctrl+Z three times for one cancel...
Do you know a way to avoid this behavior?
function onEdit(e) {
// Prevent errors if no object is passed.
if (!e) return;
var dateMetadata;
var dateKey = 'lastModificationDate';
var userMetadata;
var userKey = 'lastModificationUser';
// Get the active sheet.
var sheet = e.source.getActiveSheet();
var user = e.user.getEmail();
var date = Math.floor(Date.now() / 1000);
metadatas = sheet.getDeveloperMetadata();
for each (var m in metadatas) {
if (m.getKey() === dateKey) {
dateMetadata = m;
}
if (m.getKey() === userKey) {
userMetadata = m;
}
}
if (dateMetadata) {
dateMetadata.setValue(date);
} else {
sheet.addDeveloperMetadata(dateKey, date);
}
if (userMetadata) {
userMetadata.setValue(user);
} else {
sheet.addDeveloperMetadata(userKey, user);
}
}

Answer 1

After the script was run, when one time "ctrl+Z" is pushed, you want to undo the put value.
In your current script, after a value is put to a cell, the undo can be done by pushing 3 times "ctrl+Z".
If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.
Modification points:
When the Spreadsheet is opened from outside and modify the Spreadsheet with the script, even when "ctrl+Z" is pushed, the undo cannot be done. In your case, I thought that this can be used.
Use var sheet = SpreadsheetApp.openById(id).getSheetByName(sheetName) instead of var sheet = e.source.getActiveSheet().
Modified script:
When your script is modified, it become as follows.
From:
function onEdit(e) {
To:
function installedOnEdit(e) {
In this case, please install the installable OnEdit event trigger for the function of installedOnEdit. By this, openById can be used.
And also, please modify as follows.
From:
var sheet = e.source.getActiveSheet();
To:
var id = e.source.getId();
var sheetName = e.source.getActiveSheet().getSheetName();
var sheet = SpreadsheetApp.openById(id).getSheetByName(sheetName);
Note:
When the installable OnEdit event trigger is used, the double run of functions can be prevented by changing the function name from onEdit to installedOnEdit. Ref
In this case, unfortunately, it cannot confirm using the event object whether "ctrl+Z" was pushed. By this, the added developer metadata cannot be canceled with "ctrl+Z". Please be careful this.
As another method, of course, I think that you can also use Sheets API in your situation.
