Issue Connecting Google Drive Credentials - Error 403: Access Blocked

[Hukmi]

I am facing issue while trying to authenticate my Google Drive account within an n8n workflow.
When attempting to connect the Google Drive node using OAuth2, I am blocked by Google with the following error message:The error details state: “The app is currently being tested, and can only be accessed by developer-approved testers.” (Error 403: access_denied)

Welcome to the community @Hukmi

your Google OAuth application is in “testing” mode, which restricts access to a specific list of approved users. The standard solution is to add your Google account email address as a Test User in your Google Cloud Project. This is the most common fix for the “can only be accessed by developer approved testers” error.

When I click Sign in with Google: [image] I get the following error [image] Do I have to take any action to have my credentials verified by Google?
