Type-Error Message on OpcUa-Server

Hi @all,

for a project I try to create an OPC DA - UA converter. I used the OpcUa-Server Node. It works pretty well, but I am getting the error message in debug window "TypeError: Cannot read property 'indexOf' of undefined" when trying to write values to the server...

I have no clue how to debug. Can anyone help me?

Now I solved the problem myself... In case someone else have this problem, here is my workaround:

I used an OPC-UA client node to write the values.
msg.topic should be like "ns=1; s=NAME; datetype = String" and
msg.payload is the value

I don't understand why the server node brings the issue, but this works for me...
