Editing Debugging Bub Message in Mini Hanna Node (section)

== Step-by-step debugging guide ==
* Step A: Collect logs
  • Enable verbose/diagnostic logging for Bub and Mini Hanna during reproduction.
  • Look for surrounding events that indicate where the failure occurs (parsing, decoding, or execution).
* Step B: Inspect Bub payload
  • Retrieve the exact payload that caused the error.
  • Check JSON syntax, encoding (UTF-8), and schema conformance.
* Step C: Validate Mini Hanna input handling
  • Verify the code path that consumes Bub messages and confirm required fields.
  • Ensure optional fields are handled gracefully when missing.
* Step D: Check transformation or routing logic
  • If the payload is transformed before processing, ensure the transformation preserves required fields and formats.
* Step E: Verify downstream effects
  • Confirm downstream consumers receive a well-formed message after a fix.
* Step F: Minimal repro
  • Craft a minimal Bub message that exercises the same code path to confirm the issue is fixed.
