Dify+webhook+poll+error

I built an asynchronous processing system using Vercel + Supabase + Dify + Clerk.
The last node in Dify uses an HTTP webhook to POST results to Supabase, which are then displayed on the frontend.

I encountered an issue: when an error is reported.
If a Dify node reports an error, the entire process stops and cannot form a closed loop.
It is possible to build an error-handling loop through error branches.
However, enabling error branches for each node is too cumbersome for complex workflows.

Is there a way to allow error information to also flow directly through the business logic webhook?

Dify has the error handling for the LLM node, HTTP, Code, and Tools. You can see this link (Error Handling - Dify Docs) to learn how to use it.
