Can't edit/change description of Node

[MatthewBoss96]

Hi all!

I am currently trying to build an OPC Server. I managed in building the environment, but I get stuck on changing the description of a node.

self.variable = await self.Object.add_variable(idx, "Name", 0.0)
self.variable.write_attribute(ua.AttributeIds.Description, ua.DataValue(ua.LocalizedText("TEST")))

When I run my code, it correctly creates the variable named "Name", but then the description stays on the name of the Object. I tried to debug the write_attribute method, but it should be correct in the way I try to write the description Attribute of the variable.
Also, the server continues to run normally and I do not get any errors in the logging.

Maybe you guys have an idea where I am going the wrong direction?

Got it! Forgot to add the "Await" statement in front of the write_attribute line. Working code is now:

self.variable = await self.Object.add_variable(idx, "Name", 0.0)
await self.variable.write_attribute(ua.AttributeIds.Description, ua.DataValue(ua.LocalizedText("TEST")))
