Custom:home-feed card Configuration error

I started getting a “Configuration Error” for all 3 of my home-feed cards. Everything looks fine, I’ve compared with the latest documentation and it all looks good.

Here its my frontend code:

Here is what I have in configuration.yaml:

calendar:
  - platform: caldav
    username: !secret icloud_login
    password: !secret icloud_password
    url: https://caldav.icloud.com
    calendars:
      - "Family & School"
      - "Movie Night"
      - "Vacations"
```
