Google Drive credentials problem. App not verified, advanced URL goes nowhere

[Rey-G]

Describe the problem/error/question

My Google Drive credentials are not longer working. I am using this method for setting it up again. No-Code Architects

I’m in my Credentials Connection so no workflow is relevant here.

I set up the OAuth client okay, go to n8n Credential Connection for Google Drive, press the “Sign in with Google” button towards the advanced section and run into this screen that has “Go to n8n.cloud (unsafe)” on the bottom. Here I would expect to see permission to scopes show up but I get the black window error “Something went wrong. Please try again.”

The link shows “https://accounts.google.com/” instead of some other information forwarding me to content in this pop up window authorizing scope permissions. I click on this URL and get this error message.

This domain (n8n.cloud) is also in the OAuth Consent Screen>Branding tab and is correct according to the docs.

Thank you,

Rey

Hi, I can help.

You need to add your email in this page: https://console.cloud.google.com/auth/audience

Thanks Grot. I added it during test mode but when I change it to production mode, I no longer see my email. When I sign into Google from n8n Credentials, I find my google account but the next page looks like this:

I see, so just to check of some boxes. Have you enabled the drive api in google cloud?

And inputted your redirect url from n8n to your client. https://console.cloud.google.com/auth/clients

[Rey-G]

Yes,
in my APIs & Services, the Enabled APIs include:

and Yes.

Okay, I got it finally! Using Gemini, not another LLM, I followed the troubleshooting guide and learned the Client secret is foul. I tried again in Incognito mode and get access to the scopes to give permission to.
5 days (10s of hours), 2 forums and it is done.

Lessons:
Ask for help.
Don’t get bogged down on one bug, move on to the next of MANY steps.
This is life of a vibe and old-skool coder.
Serenity prayer acceptance.

Thank you Grot for your kindness and help.
