BadMonitoredItemFilterInvalid

[ts4iot]

I try to subscribe to Alarms and Events on a Siemens WinCC.

I use the following example as basis:
client-events.py

I adjusted the main funktion at three points:

• client = Client("opc.tcp://172.31.73.22:4862")
• obj = root.get_child(["0:Objects", "1:WinCC", "1:@LocalMachine::"])
• myevent = root.get_child(["0:Types", "0:ObjectTypes", "0:BaseObjectType", "0:BaseEventType", "2:WinCCEventType"])

After running the example I got the following result:

Requested session timeout to be 3600000ms, got 300000ms instead
Objects node is: i=84
MyObject is: ns=1;s=f|@LocalMachine::
MyFirstEventType is: i=2130
ServiceFault from server received while waiting for publish response

raise UaStatusCodeError(self.value)
opcua.ua.uaerrors._auto.BadMonitoredItemFilterInvalid: "The monitored item filter parameter is not valid."(BadMonitoredItemFilterInvalid)

Can someone help me to set the filter parameter correctly. Currently I have the filter on the default setting.
