Hello,

For someone who also runs into this: When I tried to use GetSessionUserDetailedUsage I got the following error: "System.ServiceModel.FaultException: 'Value cannot be null.

Parameter name: delivery'". Turns out the reason was because the sessionId is incorrect. When you lookup a sessionId in the UI, take the Delivery ID instead of the Session ID.

This was the code I was using:

```

   var auth = new pur.AuthenticationInfo()

   {

    UserKey = PanoptoConstants.AuthUser,

    Password = PanoptoConstants.AuthPassword

   };

   var client = new pur.UsageReportingClient();

   var pagination = new pur.Pagination()

   {

    MaxNumberResults = 100

   };

   var userId = new Guid("---");

   var sessionId = new Guid("---");

   var result = client.GetSessionUserDetailedUsage(auth, sessionId, userId, pagination);

Hi Doug, Thank you, but please keep in mind that this issue (https://support.panopto.com/s/question/0D539000063cWTSCA2) is far more important. Thank you, Erik
