TL;DR

The OpenClaw gateway crash is likely due to an unhandled promise rejection, and rolling back to version 4.2 may serve as a temporary workaround.

Guidance

1. Review the error message: The error "Agent listener invoked outside active run" suggests an issue with the agent's event processing, potentially related to the @mariozechner/pi-agent-core module.
2. Check for updates or fixes: Look for any updates or patches for OpenClaw version 2026.4.5 that may address this issue.
3. Verify the rollback: If rolling back to version 4.2, ensure that all dependencies and configurations are compatible with the older version.
4. Monitor the application: After applying the workaround or fix, closely monitor the OpenClaw gateway for any further crashes or issues.

Example

No specific code example is provided, as the issue seems to be related to a specific module or version of OpenClaw.

Notes

The root cause of the issue is unclear, and the provided information does not specify any recent changes or updates that may have triggered the crash. Further investigation into the @mariozechner/pi-agent-core module and the OpenClaw version 2026.4.5 may be necessary to identify the root cause.

Recommendation

Apply the workaround by rolling back to version 4.2, as it has been reported to resolve the issue temporarily. This will allow for continued use of the OpenClaw gateway while a more permanent fix is investigated.
