[BUG] HTTP 400 "Invalid project resource name projects/" - Day 5, No Fix

I’m a Google AI Pro subscriber and have been stuck with this error for 5 days (since Feb 11, 2026).

Error: HTTP 400 Bad Request
“Invalid project resource name projects/”

What I’ve tried (NONE worked):

  • Complete uninstall and reinstall
  • Deleted .gemini folder
  • Installed gcloud CLI, re-authenticated
  • Created new Google Cloud project
  • Disabled all MCP servers
  • Switched models (Gemini, Claude, all fail)
  • Logged out and back in multiple times

Key finding: A DIFFERENT Google account works fine on the same machine. This proves it’s an account-level server-side issue, not a local problem.

Multiple users are reporting the same issue (#1826, #1836, #1910, #1932 on GitHub).

Google team - please acknowledge this issue and provide an ETA for the fix. We are paying subscribers who cannot use the product.
