(animated) Icons in custom-animated-weather-card

Hi,

I have the problem that custom-animated-weather-card dont show the weather-icons.

grafik

Adress of the icon: ha-card-weather-conditions/icons/animated/undefined.svg

Here is the config of this card:

- type: custom:ha-card-weather-conditions
          language: de
          animation: true
          weather:
            icons_model: openweathermap
            current:
              current_conditions: sensor.openweathermap_condition
              temperature: sensor.openweathermap_temperature
              feels_like: sensor.openweathermap_feels_like_temperature
              sun: sun.sun
              humidity: sensor.openweathermap_humidity
              pressure: sensor.openweathermap_pressure
              wind_bearing: sensor.openweathermap_wind_bearing
              wind_speed: sensor.openweathermap_wind_speed

Some icons seems to be working, depending on the weather condition. E.g. the icon for “clear night” condition is not working.

Any ideas to fix this problem?
Thanks in advance,
Ben
