Request failed with status code 500 when scanning for channels

<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

I see the USB device listed but once I hit scan channels I get this message:

"

We need some more information before proceeding with the channel scan.

"

and a blank box for input but nothing works beyond that page and I get an error at the top.
