Hi team,

Our OPC UA client based on Prosys Java SDK works fine, all data is received. But client’s log are spammed by the following messages from SDK

WARN com.prosysopc.ua.client.NodeCache Missing a TypeDefinition for NodeId: ns=1;s=BINOM.RGS20.Tank_type, NodeClass: Variable, BrowseName: 1:Tank_type – [Synchronizer: opcua] com.prosysopc.ua

How we can get rid of this?
Thanks

Hi,

This must be fixed on the server side, https://reference.opcfoundation.org/Core/Part3/v105/docs/7.13 “Each Variable and each Object shall be the SourceNode of exactly one HasTypeDefinition Reference.” and here a Variable didn’t have that, thus the WARN. SDK will use a more generic UaNode implementation as a fallback, but depending on the situation it could fail later with ClassCastExceptions.
