openclaw - 💡(How to fix) Fix Regression 2026.3.31: embedded agent calls read tool without path during heartbeat polls [1 participants]

TL;DR

Downgrade to version 2026.3.23 as a temporary workaround to avoid the internal path resolution issue during heartbeat execution.

Guidance

• Verify that the HEARTBEAT.md file is correctly formatted and located in the workspace root to ensure it's not contributing to the path resolution issue.
• Check the documentation for any changes in path resolution or heartbeat behavior between versions 2026.3.23 and 2026.3.31 that might be causing the error.
• Test the read tool with explicit calls using different paths to see if the issue is specific to the heartbeat interval or a more general problem.
• Consider reporting the issue to the developers or maintainers of the embedded runner for a more permanent fix.

Example

No code snippet is provided as the issue seems to be related to a version-specific bug rather than a coding error.

Notes

The solution is based on the information provided and the fact that the issue did not occur on version 2026.3.23. Downgrading might not be feasible in all environments, especially if other features or fixes in 2026.3.31 are critical.

Recommendation

Apply workaround: Downgrade to version 2026.3.23, as it is known to not have this issue, allowing for temporary relief while awaiting a fix for version 2026.3.31.
