Web app asking user to login, even though its been deployed to be used by “Anyone, even anonymous”

[Script GS]

I've deployed a script to be used as a web app that can be accessed by "Anyone, even anonymous" and yet, if a user has not logged into a gmail account on a particular browser, its asking them to login.

Here's my manifest file -

{
  "timeZone": "Asia/Kolkata",
  "dependencies": {
  },
  "webapp": {
    "access": "ANYONE_ANONYMOUS",
    "executeAs": "USER_DEPLOYING"
  },
  "exceptionLogging": "STACKDRIVER"
}

To replicate the problem, you can visit the following link by logging out of your gmail accounts (or in a browser that does not have your gmail sign in) -

https://script.google.com/macros/s/AKfycbyayXeY_LGm7sy-J1VGvg7wfqOZYonZmKphS0F4Qz4jLZ336qsR/exec/test*

*it is required that you not change the pathInfo of the URL

Current behavior -

• When signed in: You will be redirected to https://www.google.com/
• When signed out: You'll be asked to login to your Google acc.

I'm building (or rather, though I already had built) a URL shortener service using Apps Script and oddly, it is not asking users to login when accessed from a custom domain (an iframe embedded in https://tmt.pw) but it is asking them to login once they shorten the URL and try visiting the shortened URL.

The original resources are all available here -

• The entire folder on my Google Drive
  

• A Spreadsheet that acts as the datasource

• Finally, the script itself

I've tested this on Chrome, Safari and Firefox (all on a Mac) and they all exhibit the same behavior.

I'm guessing this is something very fundamental and all I want is the web app to not ask users to login, given that it has been instructed to execute even for an anonymous user.

The script has some business with a Spreadsheet as well and so I tried making the sheet publicly editable by everyone (anyone on the internet) and it still didn't work.

Was using 1 private function (with an _ at the end of the function name) & have stopped doing that in my script - still no change; problem persists.

Don't use pathInfo property and all be fine.

You cannot use cheating in production.

Hey Alex - turns out you were right :) Rolled back to using e.queryString!

Thanks for the confirm.
