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
  option: Rainbow
  entity_id: select.wled_left_preset

Expected Behavior

Not generate an error…

Install Method


What version of WLED?

WLED 0.13.2-a0 (build 2203191)

Which microcontroller/board are you seeing the problem on?

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

I still do not get it @frenck, why do you insist WLED is not following SemVer or the standards as defined by Wikipedia?

This is clearly not a WLED issue.

Hey no reason to be insulting.

It wasn’t meant insulting, there is no nicer way to put it 🤷 The fact is that there are many versioning schemes out there. Like it or not.
