docker push fails with 'error parsing HTTP 4XX response body: unexpected end of JSON input: ""' if any error is returned by the server

[BenLubar]

This code doesn't retry the request as a GET request if an error is returned, so the body of the response is always empty:

This is a client issue and the client in this repo is not maintained. Should this be closed?

Either we close it or we do something with the client, but that'd require proper TLC; I'd leave it open but I'll take it outta 3.0 Milestone....that being said, I'm not entirely sold on the idea of adding retries to the default client.
