Description

Cron jobs with payload.kind: systemEvent fail with error:

TypeError: Cannot read properties of undefined (reading 'trim')

Environment

• OpenClaw version: 2026.3.8
• Platform: Linux

Steps to Reproduce

1. Create a cron job with payload.kind: systemEvent
2. Wait for the cron job to trigger
3. Job fails with the error above

Expected Behavior

Cron jobs with systemEvent payload should execute normally

Actual Behavior

All cron jobs using systemEvent fail with:

TypeError: Cannot read properties of undefined (reading 'trim')

Affected Jobs

• 日历同步 (Calendar sync)
• 邮件检查 (Email check)
• Daily Auto-Update

Workaround

Using payload.kind: message instead of systemEvent may work, but requires specific session configuration.

Additional Info

The error appears to be in the cron-cli module when processing systemEvent payload. The error likely occurs in one of the .trim() calls in cron-cli code.
