Accessing NodeIDs of writes from prewrite callback

[rlabbe82]

I'm experimenting with the ua server implementation to monitor for writes to send to an remote device. Based on reviewing some examples, I'm testing with implementing a callback to monitor the prewrite callback events of the UA server and taking the nodeid references in the request_params to determine the appropriate node is being written to and what value is being written by the external client.

I assumed that I could get the NodeID from the WriteValue objects that are populated in the request_params but I'm getting errors preventing me from accessing the WriteValue object attributes even though it seems I should be able to according to the class def (

opcua-asyncio/asyncua/ua/uaprotocol_auto.py

Line 7364 in a2f2636

class WriteValue:

)

Any thoughts about what I might be doing incorrect? Thanks!

Wow... Guess I should have not been coding so late at night. I must have typed it 5 different ways incorrectly.

Thanks for the second set of eyes. 🙏
