Calendar can not be added

[evendark]

Dear community,
Unfortunately, I cannot add a calendar to the “Week Planer Card configuration” in my setup when I press the “Add Calender” button.

However, the calendars are displayed and listed correctly in the main menu for calendars.

Is there a debug log that can be switched on?

I'm experiencing the same behavior. @evendark were you able to progress any further?

I notice in the HA logs I'm seeing the following error:

Uncaught error from Firefox 133.0 on Windows 10 TypeError: can't define property "entity": Object is not extensible setConfigValue (/hacsfiles/week-planner-card/week-planner-card.js:647:375) _valueChanged (/hacsfiles/week-planner-card/week-planner-card.js:647:97) handleEvent (/hacsfiles/week-planner-card/week-planner-card.js:10:6019) dispatchEvent (src/common/dom/fire_event.ts:76:7) _setValue (src/components/entity/ha-entity-picker.ts:420:16)

@evendark @glancep I am unable to reproduce this problem. Can you tell me step by step what you're doing?

As a workaround you could edit the YAML code and add the calendars that way.
