BW Telemetry widget errors on connection (RM Pocket)

[buckett]

Describe the bug

Having setup the telemetry widget it launches fine, but as soon as soon as the RX is connected the telemetry widget shows an error:

Syntax error
bad argument #1 to 'getValue' (string expected, got nil)

At this point I have to long press RTN to exit the telemetry widget.

This is with iNav 9.1 and EdgeTX 2.12.2 on a Radiomaster Pocket.
This is using the latest release 2.4 of OpenTX-Telemetry-Widget.

To reproduce

1. Open telemetry widget
2. Startup model
3. Wait until model is connect (and I assume telemetry starts getting transmitted)

Expected behavior

Widget displays telemetry from model.

Radio and model settings

Nothing interesting in the model.

inav.yml
There is no .cfg file on the TX.

Additional context

I'm trying this for the first time so unsure if this is a new bug or has been broken for some time.
The script behaves the same in the EdgeTX simulator on the pocket, but I'm unable to generate telemetry so can't get it to error.

This was happening because the telemetry wasn't correctly being sent back from the flight controller to the TX, while I did get the telemetry working it would be much better if the widget didn't crash under these circumstances.
