Getting “Error: redirect_uri_mismatch” with google_oauth2

Question

The URL\'s seem right (Last updated them yesterday):

The files too:

Answer 1

It looks like the request is hitting http://localhost:3000/auth/google_oauth2/callback, but your specified redirect URI matching the similar pattern is for https. Adding http://localhost:3000/auth/google_oauth2/callback to your list of redirects may potentially solve that issue.

EDIT: Another potential fix is including a trailing / in the corresponding redirect URIs, which appeared to work in this case.
