OPC UA Node error


We have a Module that has been running on our projects for few years but we have noticed that since we updated ignition to 8.1 we receive this error.

Caused by: java.lang.ClassNotFoundException: org.eclipse.milo.opcua.sdk.server.api.nodes.Node

Has something changed to kick up this error?

Yes. It may be as simple as recompiling your module with v8.1 dependencies. See this discussion:
