When trying to test Smart object services with soapUI.
The endpoints have been enabled in the k2hostserver.config.
The endpoints were successfully reached.

But when trying to send a request the response is this:

Resolution

Check to see if the services in the tester are working and if a 400 bad request error is raised you may have to create a new SPN.
