Node Description returning default value

I have a node which description is set in the OPC UA server like this (using the SampleConsoleServer as template):
final NodeId myObjectsFolderId = new NodeId(ns, “MyObjectsFolder_OPC_Device_id”);
myObjectsFolder = createInstance(FolderTypeNode.class, “OPC_Device”, myObjectsFolderId);
myObjectsFolder.setDescription(LocalizedText.english(“I am just a simple OPC-UA capable device.”));
this.addNodeAndReference(objectsFolder, myObjectsFolder, Identifiers.Organizes);

When trying to read the “Description” attribute of a node in the Client through:

DataValue value = client.readAttribute(target, Attributes.Description); (target = my node)

The returned value is the default . However, when connecting the UaExpert client to my server, it displays my custom description. Also when reading the “Attributes.DisplayName”, the returned value is correct: “OPC_Device”, which makes me believe I am reading from the right node.

Any help would be gratefully appreciated.

Best regards,
Ricardo

Hello,

Can you show how you create the NodeId variable named target?

Initially the most likely error is that you are somehow reading the description attribute from some other node than the myObjectsFolderId even though you already mentioned checking for the correct node.
