Error 400: redirect_uri_mismatch

[Ivory-Alpaca]

I am getting the following error after running the main method:

The redirect URI in the request, urn:ietf:wg:oauth:2.0:oob, can only be used by a Client ID for native application. It is not allowed for the WEB client type. You can create a Client ID for native application at https://console.developers.google.com/apis/credentials/oauthc

This is all that shows on screen. Any idea how to fix it? Is it something with the code?

If you choose Desktop app type, it should work.

If you choose Desktop app type, it should work.

I did that and it didn't work...i keep getting this error

You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure.
You can let the app developer know that this app doesn't comply with one or more Google validation rules.

Any solutions?
