Bug Report

All sessionTarget: "isolated" cron jobs fail immediately with:

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

First appeared: 2026.5.18 (May 18, 2026) Still present: 2026.5.19 Last working: 2026.5.12

Details

  • Jobs fail in ~90-250ms — the agent never starts
  • The error occurs in the isolated agent runner initialization, before any agent turn begins
  • Affects ALL isolated cron jobs regardless of:
    • delivery mode (none or announce)
    • sessionKey presence
    • wakeMode (now or next-heartbeat)
  • Jobs with sessionTarget: "main" (systemEvent payload) are unaffected
