Cannot integrate caldav through manual yaml configuratio

Configuration
1

Hi everyone,
I have tried to integrate caldav through manual yaml configuration, but I cannot see any caledar entity after a yaml configuration reload.
What am I doing wrong?

The caldav provider is nextcloud and it works normally on all the clients. The login does not require a one-time-password.

System configuration:

  • Home Assistant Core on Python Venv
  • Version: 2023.11.2

configuraiton.yaml:

calendar:
  - platform: caldav
    username: home
    password: !secret caldav
    url: https://cloud.mydomain.com/remote.php/dav

secrets.yaml:

caldav: "my-password"
