MAAS doesn't have a consistent error response format in the API

[Jason Hobbs]

MAAS is good about returning HTTP Error codes in error conditions, but it lacks a consistent format for error message content or type. Some errors cause plain/text strings to be returned, some cause application/json strings to be returned, some have no content at all.

MAAS should have a consistent format, probably a json object, something like

{
   errors: [{"message": "Frobnication failed.", "code": 42}]
}

This would allow API consumers to have generic error handling and reporting.

Also, this should be documented.

I have often thought the same thing. We need to return json exactly as you suggest I think.

While we recognise the inconsistencies, improving this would change the API in ways that go beyond a simple bugfix. This item is added to our internal backlog for further prioritisation (internal ref. PF-3904)
