It simply means that your Awesome Table's linked Google Sheets datasource:
- Was deleted (inadvertently or intentionally) or
- You’re running the Advanced Summary add-on that references a datasource that is owned by someone else and you don’t have read-access to the file.
ScriptError: ... perhaps it was deleted
Please make sure that:
1.) The pertinent Google Sheets datasource is not deleted.
2.) If it's not deleted, unlink the form, then relink to a spreadsheet datasource. More about these procedures from Google Support's help.
Finally, update the Google Sheets datasource with the new tab (sheet) name in the AwesomeTable editor by following steps 3 - 4 of this tutorial.
