Response can't be shown as JSON, although it should be
I'm pretty new to REST-testing, and I'm not very "technically".
REST-response gives "The content you are trying to view cannot be viewed as JSON".
RAW gives the header and a long string, copying this string and viewing it in JSON Viewer in Notepad++ shows that it is JSON-format though. SoapUI decides that it is content-Type: application/octet-stream.
Developer says that there must be something wrong with the JSON Viewer in SoapUI?
What could be wrong?
