WLED: HA Service call to WLED entities works but generates KeyError: 'b'

What happened?

I’ve recently upgraded from 0.13.1-b6, since then after each HA service call to a WLED entity (i.e. turning off the master, selecting presets) I’m getting a get a toast notification with an error in the HA GUI and a new entry in the error log, the action however completes successfully.

This stops HA scripts from completing causing issues in automations.

To Reproduce Bug

Example service call:

service: select.select_option
data:
  option: Rainbow
target:
  entity_id: select.wled_left_preset

Expected Behavior

Not generate an error…

Install Method

Anything else?

Self-compliled with -D USERMOD_MULTI_RELAY HA 2022.3.8 (same issue in 2022.4.0b3) Deleting/adding the WLED integration makes no difference
