Code Issues Proposed changes

Return 422 if entity from request body cannot be processed

Browse Source 
If a group/project/account which is referenced in the body of a request
cannot be found or is not processable the response code should be '422
Unprocessable Entity'. At the moment we are throwing '404 Not Found' or
'400 Bad Request'. '404 Not Found' is wrong since this status code must
only be used if the resource from the URL is not found. '400 Bad
Request' would be okay, but should rather be used if the request body
is not parseable.
