I'm trying to provide some meaningful feedback to the end user when he makes attempts to create a repository using the GitHub v3 API. It's a bit hard to make sense of the exception that I get when a repository by the given name already exists. The JSon output from GitHub looks like this:

{"message":"Validation Failed","errors":[{"field":"name","message":"name is already taken","code":"custom","resource":"Repository"}]}

which seems OK. But the RequestException that I get back will only print:

"Validation Failed (422): Error with 'name' field in Repository resource"

In the RequestException there's a RequestError with a list containing one FieldError. The field error lacks a message field and hence contains only:

{"field":"name","code":"custom","resource":"Repository"}

I think the problem is twofold. First of all, the 'message' field should be added to the FieldError class, second, an issue should be reported against the Git v3 API that the code = "custom" is inconsistent. According to the documentation [1], it should really be "already_exists"
