Have you triggered the read node? Did you connect a debug node to the output of the rad node & check the debug panel? What did you see?

I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.

It doesn't look like an error. Can you fully expand the payload and fins object

I don't see an error - the result is `-26215` for `D100`

Why do you think there is an error?
