Hi Han, I read the output and checked the code. The issue is with your
implementation of API and let me help you understand how it works briefly
and how you may fix it.
The response object is not correct. It should send the output in a response
key. It breaks because it assumes there would be a "response" key in the
received response json. Likely the issue is incorrect use of annotations in
your response class. Please check against other API response classes, the
result should be in a key which has response word, for example:
{ "deployvirtualmachineresponse" :
{"id":"d795f1d5-7f2c-446a-a5a4-9e374eb96590","jobid":"8910c383-8e96-443f-b3af-6e0171b33934"}
}
In the above response example, the serialized object is returned as json,
cloudmonkey looks for a key that has "response", in this case
"deployvirtualmachineresponse", and outputs using one of its display
methods (table, json or default/key-value outputs).
Hope this helps.
Regards.
