WLED - Changing LED type causes errors in home assistant

[Gaff]

The problem

I changed my WLED strip from RGBW to RGB LEDs and got the error below.

Reloading the WELD controller seems to have fixed the issue.

Apprecieate this is a fairly minor / niche error, but logging it just incase it's of interest.
