Has anyone found a reliable fix for the ‘invalid_grant’ error in n8n’s Google nodes without going live (Production mode)? The refresh token keeps expiring or getting revoked, and it’s driving me crazy! Any creative workarounds or hacks to keep it stable in Testing mode would be super appreciated.
Thanks for the response! I’m weighing my options, would it be more straightforward for a non programmer to push the app to production or switch to using a Google serving account?
Which path would you recommend?

Hey, there is no issue in switching your app to Production, it’s the easiest fix and doesn’t require any official verification - just flip a switch. If you still notice your credentials expiring, you might need to generate a new Secret, but that should be all.
