I'm not sure how preconfigured exceptions like HTTPUnprocessableEntity
handle data but
if you return a custom HTTP Response with status=422 and json data it
works.
But most JS Frameworks do not automatically parse the orginal json body if
the HTTP
status is not OK (200 ... 299). You will have to get the body and parse the
json manually in
your frontend code.
Maybe that's the issue here?
