I have some messages being post to service bus topic. Those messages have some custom properties embedded upon them and we wanted to put filter on the subscription created on that topic.
My properties were like this :
event-type,
event-sub-type
Notice the ‘-‘ character in the name of properties.
But my filter was just wasn’t working at all. What could be reason behind it?
Wanted to create a subscription with filter rule but it didn’t worked.
