Hi,

I ran across an issue with the REST API that responded with a 200 OK when I think it should respond with an error.

If I try to PUT this to an existing issue:

{ "issue": {
 "assigned_to_id": "19" 
 }
}

it will respond 200 OK even if it can't change the assigned_to_id to 19, for instance if user ID 19 does not have an assignable role on the project. Because the API reported a 200 OK, this led to a lot of confused debugging. A 422 return with appropriate error message in the body might be more useful.
