Goal: Determine which underlying Canva validation rules produce the generic HTTP 400 status codes observed in the Logs tab when a Canva App deployment fails after manifest syntax passes.

Uncertainty: The public error‑code reference lists manifest‑level codes but omits many runtime exception strings, leaving developers to infer causes from free‑form messages.

Which validation rules correspond to the generic 400 errors?

Are there undocumented sub‑codes or internal identifiers that could pinpoint the exact failure?
