WLED Integration not working with HA, returning error 254

Sometime between Halloween (Oct 31) and now (Dec 3) the WLED integration is no longer working and returning an error 254. Since WLED hasn’t changed since May, I suspect it might be something to do with HA. For the time being, I’m working around the issue using MQTT to turn the WLED lights on and off. I’d like to go back to the original integration as there are more options for HA control. Any possibility I’m doing something wrong?

WLED 0.14.4 (May 2024)
HA 2024.11.3
Running on Intel x86 platofrom with HA OS 13.2

In the dashboard I get the following when trying to switch WLED to ON:
Failed to perform the action light/turn_on. 254

In Node Red, I get:
12/3/2024, 8:09:49 AM[node: WLED Lights]
msg : error
“HomeAssistantError: 254”

Best Regards
