Hi, I'm helping a user to better clarify the use case of the GetServicesForFilter WebAPI.

There are a number of services that the user has created in Production (in the '000). And each service has a handful of properties. One of the properties is as follows:

Now we would like DataMiner to return the Service whose value for this property is of a particular value:

Using ConnectApp we obtain a GUID, then we send the GetServicesForFilter request following via PostMan:

But we got the following error:

{
    "Message": "Error trapped: Object reference not set to an instance of an object.",
    "StackTrace": "",
    "ExceptionType": "Skyline.DataMiner.Web.Common.WebApiException"
}

We need some advice on whether we using this WebAPI call correctly?
