The error tells everything. You should pass the parameter "ProjectId" when you test the service.
I noted that you are using postman, which should be the API testing tool, to test the service.
It would be an easier way to do post through "Form" within setting the "Content-Type" property to "application/x-www-form-urlencoded".
That way, you will not forget the parameters since you will find them all in the text boxes.
I am using another testing tool but basically they are the same.
Hope this can help you.
