Are these values always present on the response? should some of these be optional?

We have express error type in clientRoutes catch all handler.

  result = _.extend({}, result, {
    message: err.message,
    name: err.name || 'BitGoExpressError',
    bitgoJsVersion: version,
    bitgoExpressVersion: pjson.version,
  });

I don't think these are failures, they are warnings. The code quality is failing due to some different error. I see them on other PRs as well.
