Hi,
I'm trying to subscribe Prosys OPC UA Simulation Server 5.2.2 simulation folder just using iiot-opcua nodes. Using a "read node" I can read all values from tags of simulation folder but when I try to subscribe same tags using a "subscribe node", I get a error message.
My intention is subscribe tags instead call read node periodically:

If I enable "Send Just Values" listener node works but I didn't receive tag name or aditional data.
Any suggestions?
Node-RED and all nodes are updated.
