Account-specific login failure: error_code=911009 OPERATIONS_NOT_FOUND

Google Antigravity
1

Antigravity login fails only for one Google account. Another Google account logs in successfully on the same machine, same IDE install, and same network.

Environment:

  • OS: Linux x64
  • Antigravity IDE: 1.107.0
  • IDE commit: 4e2e10a9285aefbdcb898ae5e50dde45e9c7f505
  • Antigravity CLI: 1.0.4

Failing behavior:

  • OAuth completes
  • Antigravity then fails during account setup / eligibility validation
  • UI shows an unexpected account setup/login error

IDE auth.log:
Error confirming user for service: Could not find operation p35-970128760440-ca7f274c-d0c9-44b3-ac33-978329273271-u.
Auth state changed to: loginError
Error handling OAuth response: Do not know how to serialize a BigInt

CLI/backend log:
code: 404
status: NOT_FOUND
reason: OPERATIONS_NOT_FOUND
domain: managedprojects.googleapis.com
subject: ?error_code=911009&operation=p35-970128760440-ca7f274c-d0c9-44b3-ac33-978329273271-u

Troubleshooting already done:

  • Updated Antigravity CLI
  • Verified IDE update endpoint says current
  • Cleared local Antigravity CLI/project state
  • Checked /etc/hosts for cloudcode/googleapis overrides
  • Confirmed another Google account works on the same machine

This looks like an account-specific onboarding/eligibility backend state issue.

Still can’t log in

I’m facing a similar issue with Antigravity CLI, the log shows
