Answer 1

Sharing a very simple copy-paste solution that worked for me.

I copied whatever I was specifying in my code as redirectUri i.e. "redirect_uri": "http://127.0.0.1:3001/" and pasted the value of this key inside the Google settings that ask for Authorized redirect URIs. This way I'm ensured that both the parameters are same.

If the url was computed, I would console.log() it and copy it from the console window before pasting it in for google settings.
