Workaround: Showing Log in Web Apps to Apps Script Dashboard using Javascript

Wed, 29 Jul 2020 09:24:27 +0900

I have already reported for showing the log to “Apps Script Dashboard” when it requests to the Web Apps. Ref In order to show the log to “Apps Script Dashboard” when it requests to the Web Apps, it is required to use the access token. But in the current stage, when the access token is used for XMLHttpRequest and fetch of Javascript in the request headers, the error related to CORS occurs. So, in this report, I would like to propose the workaround for resolving this issue.
