Washing machine status widget

Hi, everyone.

I get the following error on the UI when trying to install this widget and the Dishwasher Status :

Installation of add-on 116621 failed

On the Karaf console I get the following:

12/26/2022 20:45:52.656 [ERROR] [mmunity.CommunityUIWidgetAddonHandler] - Widget from marketplace is invalid: Couldn't find the widget in the add-on entry

I installed other widgets from Rich Koshak and Thomas Lauterbach without problems.
I’m running OpenHAB 3.2 (stable) on a Raspberry Pi 4B with CentOS 8 (64bits).

Does anyone have any idea why this may happen?
