What i would do is apply custom error handling on your REST service. This enables you to read both the last error but also the http response content. It could be that the server returns a non 200 code e.g. when you are unable to login (401?) which Mendix then interprets as an error and thus causes a rollback of your microflow. Because of the rollback the response is not logged cause you to miss your ‘failure’ string.
Did you add a Content-Type header? Http status code 415 means
