Hi I'm having similar issue on cap 6 page 152, in fact all the exercices in this cap are with the same error, error 400 (unexpected error).
But if I try to access the url in the browser the service is show, but seems like de API service from the openshift. I'm using the brand new student guide for Openshift 4.0
Im my case was just a problem in the VT platform, not an error at the student guide.
