unable to receive events after update

[PvanIeperen]

At the moment I work on a client that must connect to a server that is running on a robot form another team in our company. This team is writing the server in C++ with the open62541 library. And we are using the .Net library from OpcFoundation.NetStandard 1.4.371.96.

The robot team has updated their library to the newest version because they need it for the HMI of the robot system.
After this update the events are not working anymore. Before the update everything was working.

I need to figure out how I can change the client in such a way that I can receive the events again.
The strange thing is that UAExpert still receives the events from the server after the update.
Does the .Net library need a minimum amount of event property field to be filled out?

If I create a plc (B&R) that fire opcua events than our software is still working.
It is just with the update version of the open62541 library.

Is someone familiar with this issue? Can someone think of some possible hints that are use full?

The underlying cause was identified to be an invalid event filter.
