Error 400 | Google | n8n inserting too many characters in OAuth Redirect URL

[guilhermerezende]

Hello everyone,

I’m having a problem logging into my Google account when I’m creating a credential for Google Sheets.

Error 400: redirect_uri_mismatch

I noticed that n8n is inserting an extra character in the OAuth Redirect URL which is conflicting with Google Cloud.

I would like to know if anyone has experienced this error and found a solution.

How do I fix this in n8n? I wouldn’t like to have to create another domain for my website.

Regards

Hey @guilhermerezende,

Welcome to the community

Can you double check your WEBHOOK_URL it looks like you possibly have an extra . at the end.
