What's Wrong?

• Scheduled triggers not auto-running on cron schedule:

Trigger ID: trig_01LAgwXGG4z6W5TdoYWFD9cq
Cron: 0 16 *
Has missed auto-run on 2026-04-01 and 2026-04-02 at 16:00 UTC.
The next_run_at field never advances after the scheduled time passes.

• Manual trigger via API returning 500:

POST to /v1/code/triggers/{trigger_id}/run returns:
{"error":{"message":"An internal server error occurred","type":"api_error"}}
Request IDs: req_011CZdPmP622JKS2h6PFacrp, req_011CZfFWxCyrqRysokC3pviK

The request IDs are especially useful for Anthropic to look up the server-side logs.

What Should Happen?

• Scheduled triggers should auto-run at the specified cron time (0 16 * = 9am PDT daily)
• The next_run_at field should advance to the next day after each successful run
• POST to /v1/code/triggers/{trigger_id}/run should return 200 and kick off the agent session

{"error":{"message":"An internal server error                                                                       
  occurred","type":"api_error"},"request_id":"req_011CZdPmP622JKS2h6PFacrp","type":"error"}                           
  {"error":{"message":"An internal server error                                                                       
  occurred","type":"api_error"},"request_id":"req_011CZfFWxCyrqRysokC3pviK","type":"error"}

Steps to Reproduce

1. Create a scheduled trigger via POST /v1/code/triggers with a cron_expression (e.g. "0 16 *")
2. Wait for the scheduled time to pass
3. Check the trigger via GET /v1/code/triggers/{trigger_id} — next_run_at does not advance
4. Try to manually run via POST /v1/code/triggers/{trigger_id}/run — returns HTTP 500
