Middleware like plug

I already tried the Plug.ErrorHandler, but it re-raises the error as the documentation points

I need a solution to enrich the error message and return a JSON

How did you try that? Because the http request should receive whatever you send as response in the handler. It shouldn’t matter that the error is reraised (e.g. to get properly logged).

See Phoenix.ConnTest — Phoenix v1.7.7 for testing those.

Raising an error is not the way you do things in elixir.

Instead of raising, you can return a tuple in the format {:error, :not_found} and handle it in a fallback controller .

While the latter is a viable option the former is not generally true. Exceptions are the only way to handle errors from LV right now (via Plug.ErrorHandler) and phoenix itself for a long time didn’t have action_fallback while already having means of handling exceptions.
