TypeError creating data node and formatting homie id

[Ltty]

When setting up your server to connect a Tuya NWT Dehumidifiert to MQTT, I get the following exception. Looks like the server is for some reason unable to create a homie id. Any idea what might go wrong?

Scratch that. Redownloaded the config from the tuya cloud and the issue is fixed. Seems like not all fields got fetched in the first configuration run

Yes you need to add the device to the cloud and give it 24h or so for the types to get updated. It's weird. I guess there was nothing in the device name at this stage yet.

I would also add that the code is still experimental but mostly works for me. Let me know if you discover issues. There may well be.
