4.14 Minefield

Key point

openclaw 4.14 conflicts with lossless-claw, causing the agent to freeze.

Details

As soon as openclaw was updated to 2026.4.14, lossless-claw broke on every message, and the agent became completely unresponsive.

The error was Context engine 'lossless-claw' factory returned an invalid ContextEngine: info.id must match registered id 'lossless-claw'., and it occurred identically across all channels including Discord / Telegram / Web.

The fix is to disable lossless-claw in openclaw.json and revert to the default context engine. Doing this restarts the agent immediately, but the lossless context feature becomes temporarily unavailable.

bug #66591 has already been filed, so the dev team is aware of the issue. The author warns to avoid this version and stay on 4.12.

Key points are as follows.

  • Failure occurs right after the 4.14 update
  • Agent fails to start when using lossless-claw
  • Temporary workaround: revert to the default context engine
  • The rule of thumb offered is that waiting 48 hours after an update is safe until things stabilize
