Hey! I am having trouble connecting my n8n workflow to Google Docs. I continue to get this error every time:

This error appears right after linking the credential, clicking “Sign In With Google”, selecting my account, and hitting “allow.”

This appears under more details: {“error”:“redirect_uri_mismatch”,“error_description”:“Bad Request”}

I’ve tried multiple different things to problem solve. I’ve deleted and re-created the credential. I’ve deleted and re-made the client in Google Console. I’ve deleted and re-picked my scopes. I’ve tried asking both Chat and Claude. Any insight would be SUPER helpful. Thank you so much!

Hi @Social_Carry

Have you had it working before or with other Google services?

Which version of n8n are you running?

Hey! I have never had google docs working before but I use sheets and Drive all the time no issue. Online

Running version n8n@2.1.1

Hi @Social_Carry

Best way forward is to update your n8n instance to the newest stable version.

That can be done here: n8n.cloud

After it has updated, retry getting the credentials working :slight_smile:

YOU MY FRIEND ARE AMAZING! I cannot believe it was that simple and I missed it. I thought I had updated the workspace before when I restarted. Truly, thank you haha
