Overview
I will share the solution when I encounter the following error when running GAS(GoogleAppsScript).
Exception: The document is inaccessible. Please try again later.
methodName1 @ ScriptName.gs:38
methodName2 @ ScriptName.gs:20
Solution
I was trying to create a copy of a google document with the following code.
The problem was that the google document I was trying to load was actually “Word format” not “Google Document format”.
var documentId = "enter your google document file name"
var file = DriveApp.getFileById(documentId).makeCopy('NDA_' + lastname);
var nda = DocumentApp.openById(file.getId());
Other solution?
In the StackOverflow below, the solution of changing the default account of the Chrome browser was answered, but it was not effective in my case.
