Handling of 500 errors

[asaunier]

(Just a question, perhaps the current behaviour is OK)

When making AJAX requests to the API from the UI, if the API crashed because of some error (eg. missing field in DB), Angular's $http actually returns an object with "status: 500" (which is correct) and a data properties containing an HTML output with the 500 error returned by the API.
Should we do something in order to get a cleaner JSON output instead of the raw pyramid 500 page?

I agree we should return json.

[tsauerwein]

Yes, you are right. JSON would be cleaner.

Same with 403 errors returned by the API when a user tries to make a write action from the UI without being authenticated.
