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.
