GetOPCNodeList java.lang.IllegalArgumentException: Value underflow

[vladislav-klass]

when fetching node list with GetOPCNodeList from my opcua server, I get this error message if I set Recursive Depth > 6. If Recursive Depth <= 6 everything works fine.

org.opcfoundation.ua.common.ServiceResultException: Bad_InternalError (code=0x80020000, description="2147614720, Value underflow") at org.opcfoundation.ua.transport.tcp.io.TcpConnection$ReadThread.run(TcpConnection.java:1006) Caused by: java.lang.IllegalArgumentException: Value underflow at org.opcfoundation.ua.builtintypes.UnsignedInteger.<init>(UnsignedInteger.java:126) at org.opcfoundation.ua.encoding.binary.BinaryDecoder.getExpandedNodeId(BinaryDecoder.java:709) at org.opcfoundation.ua.core.EncodeableSerializer$83.getEncodeable(EncodeableSerializer.java:2501) at org.opcfoundation.ua.encoding.utils.AbstractSerializer.getEncodeable(AbstractSerializer.java:136) at org.opcfoundation.ua.encoding.utils.SerializerComposition.getEncodeable(SerializerComposition.java:105) at org.opcfoundation.ua.encoding.binary.BinaryDecoder.getEncodeableArray(BinaryDecoder.java:622) at org.opcfoundation.ua.core.EncodeableSerializer$84.getEncodeable(EncodeableSerializer.java:2529) at org.opcfoundation.ua.encoding.utils.AbstractSerializer.getEncodeable(AbstractSerializer.java:136) at org.opcfoundation.ua.encoding.utils.SerializerComposition.getEncodeable(SerializerComposition.java:105) at org.opcfoundation.ua.encoding.binary.BinaryDecoder.getEncodeableArray(BinaryDecoder.java:622) at org.opcfoundation.ua.core.EncodeableSerializer$86.getEncodeable(EncodeableSerializer.java:2579) at org.opcfoundation.ua.encoding.utils.AbstractSerializer.getEncodeable(AbstractSerializer.java:136) at org.opcfoundation.ua.encoding.utils.SerializerComposition.getEncodeable(SerializerComposition.java:105) at org.opcfoundation.ua.encoding.binary.BinaryDecoder.getMessage(BinaryDecoder.java:1062) at org.opcfoundation.ua.transport.tcp.io.TcpConnection$ReadThread.run(TcpConnection.java:928)

I fetched the same data with the most recent release of open62541 client and it works fine. I can retrieve the full node list at any depth with that client.

I suspect that the server might be returning large arrays, complex structures, or certain NodeIds or references that the legacy UA-Java stack cannot correctly parse.

Anyone managed to run the extension with UA-Java version > 1.3.343?

Running the extension in the latest nifi 2.0 container.

Since this issue is likely due to the unmaintained UA-Java Stack dependency, I am trying out this repo instead
now: https://github.com/linksmart/nifi-opc-ua-bundles?tab=readme-ov-file

It's based on the actively maintained Eclipse Milo OPCUA Java stack + SDK, instead of the outdated and unmaintained UA-Java Stack
