Summary

After upgrading from 2026.2.22-2 to 2026.2.23, the google-antigravity plugin fails to authenticate, throwing Invalid Google Cloud Code Assist credentials. Use /login to re-authenticate. despite valid existing tokens. This causes the main model invocation to fail and triggers a system-wide hang (pseudo-deadlock).

Steps to reproduce

1. Environment: Ensure google-antigravity is configured and working on OpenClaw 2026.2.22-2.
2. Action: Execute openclaw upgrade to version 2026.2.23.
3. Trigger: Restart the gateway and attempt any task requiring the main model.
4. Observation: Gateway logs immediately report the credential error; the agent process enters a non-responsive

Expected behavior

Seamless transition of credentials between minor versions; driver should remain compatible with core auth-bridge.

Actual behavior

Auth handshake fails immediately. Re-running /login does not persist or resolve the state in the new version.

OpenClaw version

2026.2.23

Operating system

macOS 26.4 beta 1

Install method

npm globe

Logs, screenshots, and evidence

Impact and severity

Critical. System is rendered unusable for users relying on Google Cloud Code Assist backends.

Additional information

This appears to be a compatibility break in the 2026.2.23 core's handling of the Antigravity driver interface. The core may have introduced strict credential validation or a new handshake protocol that is incompatible with the legacy driver's token storage logic.
