Bug type
Regression (worked before, now fails)
Summary
read and write tools fail with "Missing required parameter" after ~15 minutes of session activity
Steps to reproduce
- Start a new OpenClaw session
- Use
read tool successfully (e.g., {"file":"memory/2026-03-25.md"})
- Continue conversation for approximately 15 minutes
- Try
read tool again with the same parameter format
- Error occurs: "Missing required parameter: path alias"
Expected behavior
read and write tools should continue to work throughout the session, accepting the file parameter correctly.
Actual behavior
After ~15 minutes, both read and write tools return:
{
"status": "error",
"tool": "read",
"error": "Missing required parameter: path alias. Supply correct parameters before retrying."
}Even when explicitly providing the file parameter, the system reports it as missing.

04:42:29+00:00 error [tools] read failed: Missing required parameter: path alias. Supply correct parameters before retrying.Impact and severity
Medium - Tools become unusable after short session duration, requiring gateway restart
Additional information
- Error first observed: 2026-03-26
- Frequency: Consistent after ~15 minutes
- Workaround exists but disrupts workflow
exec tool continues to work normally when read/write fail- Workaround: Use
exec + cat to read files, exec + echo to write files
- Manual
openclaw gateway restart restores read/write functionality
- Issue is reproducible: happens consistently after ~15 minutes of session activity
