Need help Google OAuth2 credential fails

I’m on n8n Cloud.

Google OAuth and Google Gemini credentials fail with:

Unexpected token ‘S’, “Salted__…” is not valid JSON.

I’ve deleted all Google credentials.

Sir kindly double check your access token and secret code that generated from google, its json file.

The client id and secret can connected succesfully, after that i press connect google its instanly pop up the error

Kindly please check your google console > APIs & Services > OAuth consent screen > Clients > OAuth 2.0 Client IDs (Inside make sure you add your n8n webhook to Authorized redirect URIs. And in Audience make sure your gmail you used are listed as Test User.
