node OPCUAServer is not working => how to use namespaces

[federicab20]

Hello, I'm working with library node-red-contrib-opcua but since this morning the Node-red flow has stopped working and I don't understand the problem. The OPCUA server in the 'custom nodeset directory' field presents the directory containing the .xml file that it must read to insert namespace values, but seems that the file is not read because I get ns = -1 instead of ns = 5, do you have any idea what happened? I am sending you the screenshots to understand better.

the file contains:

I try to update the library from version 0.2.266 to 0.2.270 but without success.

Thank you

New node-opcua validates nodeset xml and I expect it is not accepted / there is nothing to import.

I don't understand. I want to add namespaceUri and so I add the file xml to modify the OpcUA Information Model. But the system, even if I update the library to new version, isn't be able to read the file, insert the new namespaceUri into the namespace array and then insert variable in OPCUA structure. How do I resolve it?

I have the following situation:

There is also registerNamespace in the opcuaCommands

I didn't think about it before, thank you

Your nodeset XML file is not valid. I added there a bit more definitions like alias and after that it will fail to load.

This way it will work:

There are commands: getNamespaceIndex and getNamespaces.

Thank you very much for you explanation. Just a notification: my nodeset worked, I had seen examples where it was modified in that way. But that's not a problem, this other solution is fine. Thank you.
