func UnwrapError

func UnwrapError(logger log.Logger) endpoint.Middleware

UnwrapError middleware to move a business error found in the response parameter into the error parameter. This function should be called after circuit breaking and/or retry logic so a business error will not trigger those middlewares. It's use is primarily as outer shell middleware at the client end so a client method implementation only needs to test for error instead of both error and response payload business error.
