Nope, that didn’t work. :expressionless:

Hitting a non-existent endpoint with curl:

HTTP/1.1 404 Not Found
cache-control: max-age=0, private, must-revalidate
content-length: 1333
content-type: text/markdown; charset=utf-8

# Phoenix.Router.NoRouteError at POST /does_not_exist

Exception:

    ** (Phoenix.Router.NoRouteError) no route found for POST /does_not_exist (MyAppWeb.Router)
# <snip>

And it’s returning markdown text? Why?

I am still trying to understand how do I just intercept ALL errors and wrap them in keys in a resulting JSON object.
