Set ActivityParties to Appointments using Dynamics connector for LogicApps

[LeoGonzalez]

Hello everyone,

I have a LogicApp flow and I'm trying to create an appointment using the Dynamics connector. I'm able to create the appointment, but I cant find a way to set the RequiredAttendees field. That field is expecting for a collection of ActivityParties. I was able to do this using Xrm dll, following the instructions in this link.

However, I tried many ways to set the required attendees using the connector for LogiApps. The code snippet that makes more sense to me is this (it's a simplied version):

{
    "inputs": {
        "host": {
            "connection": {
                "name": ""
            }
        },
        "method": "post",
        "body": {
            "scheduledstart": "",
            "subject": "",
            "actualend": "",
            "description": "",
            "_requiredattendees_type": "activityparties",
            "_requiredattendees_value": [
                {
                    "_ownerid_type": "systemusers",
                    "_ownerid_value": "{GUID}",
                    "_partyid_type": "contacts",
                    "_partyid_value": "{GUID}"
                }
            ],
            "createdon": "",
            "modifiedon": "",
            "statecode": ""
        },
        "path": "",
        "authentication": ""
    }
}

Most of my attempts thrown the next error:

{
  "status": 400,
  "message": "A value must be provided for item.",
  "source": "dynamicscrmonline-eus.azconn-eus.p.azurewebsites.net",
  "debugInfo": "clientRequestId: {GUID}"
}

Any idea about how can I set values for that field using Dynamics connector for LogicApps?

Thanks in advance.
