Problem Introduction
Catch Hook works in tests but fails with live production payloads.
Why It Happens
- •Live payload differs from sample payload
- •Field mappings are brittle
- •Destination endpoint is slow or unstable
- •No retry-safe handling
Step-by-Step Fix
- 1Compare test payload and live payload fields.
- 2Update mapping with optional/null-safe guards.
- 3Validate endpoint response behavior and timing.
- 4Add event correlation IDs in logs.
- 5Replay failed tasks with corrected mappings.
Common Mistakes
- •Assuming sample payload equals production payload
- •Hardcoding field paths
- •No dead-letter flow for persistent errors
Debugging Workflow
Task history -> payload diff -> endpoint trace -> task replay validation.
Preventive Best Practices
- •Version field mappings
- •Track failed-task patterns
- •Document critical mapping dependencies
Works with webhooks and other async event systems (including AI callbacks).
Instead of guessing, inspecting the exact payload and headers can help debug faster. Tools like Hookmetry support this workflow.
