What's Wrong?

Trigger trig_01FzzBtAJS267rY9ZxPoEYSv was created successfully (HTTP 200)
and GET returns healthy config with all fields populated. However,
POST /v1/code/triggers/{trigger_id}/run consistently returns HTTP 500:

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

Attempted 3 times over ~20 minutes — same result each time.

Trigger config:

• Environment: env_0136T83xnctG8FAuA2HfLchV (anthropic_cloud)
• MCP connections: Granola, Slack, Notion
• Git source: https://github.com/azher-ratnani/fleek-knowledge-base
• Model: claude-sonnet-4-6
• Cron: 53 3 * (scheduled runs not yet tested)
• Created at: 2026-04-07T10:01:00Z

Request IDs:

• req_011CZpDdQnNLrFM9D9Ba37UH
• req_011CZpDdqpWXZAYMZFt1Xj2r
• req_011CZpFXYhBpLjJBPBnCAiv9

What Should Happen?

The trigger should run the scheduled job.

Steps to Reproduce

1. Create a remote trigger with MCP connections (Granola, Slack, Notion) and a git source:

• POST /v1/code/triggers with valid body (returns HTTP 200)

1. Verify trigger exists:

• GET /v1/code/triggers/trig_01FzzBtAJS267rY9ZxPoEYSv (returns HTTP 200 with full config)

1. Attempt manual run:

• POST /v1/code/triggers/trig_01FzzBtAJS267rY9ZxPoEYSv/run

1. Returns HTTP 500 consistently across 3 attempts over 20 minutes
