Sensor template for weather.get_forecasts appears to return a String instead of an array

The problem

Hello,

I have the following template for use with Tileboard to fetch hourly weather from Environment Canada.

template:      
  - trigger:                                              
      - platform: time_pattern
        hours: "/4"                                               
      - platform: homeassistant
        event: start
      - platform: event
        event_type: event_template_reloaded
    action:                   
      - service: weather.get_forecasts
        data:           
          type: daily
        target:                                                                                                
          entity_id: weather.ottawa_kanata_orleans
        response_variable: daily
    sensor:
      - name: Weather Forecast Daily
        unique_id: weather_forecast_daily
        state: "{{ states('weather.ottawa_kanata_orleans') }}"
        attributes:                                           
          temperature_unit: "{{ state_attr('weather.ottawa_kanata_orleans', 'temperature_unit') }}"
          forecast: "{{ daily['weather.ottawa_kanata_orleans'] }}"

Using the following

{{state_attr('sensor.weather_forecast_daily','forecast')}}

The above used to give me an array of objects back, but now I just get a string.

{'forecast': [{'datetime': datetime.datetime(2024, 8, 12, 15, 0, tzinfo=tzutc()), 'precipitation_probability': 30, 'condition': 'lightning-rainy', 'temperature': 22.0, 'templow': 13.0}, {'datetime': datetime.datetime(2024, 8, 13, 15, 0, tzinfo=tzutc()), 'precipitation_probability': 0, 'condition': 'sunny', 'temperature': 27.0, 'templow': 15.0}, {'datetime': datetime.datetime(2024, 8, 14, 15, 0, tzinfo=tzutc()), 'precipitation_probability': 30, 'condition': 'rainy', 'temperature': 28.0, 'templow': 14.0}, {'datetime': datetime.datetime(2024, 8, 15, 15, 0, tzinfo=tzutc()), 'precipitation_probability': 0, 'condition': 'sunny', 'temperature': 28.0, 'templow': 15.0}, {'datetime': datetime.datetime(2024, 8, 16, 15, 0, tzinfo=tzutc()), 'precipitation_probability': 0, 'condition': 'partlycloudy', 'temperature': 28.0, 'templow': 18.0}, {'datetime': datetime.datetime(2024, 8, 17, 15, 0, tzinfo=tzutc()), 'precipitation_probability': 60, 'condition': 'rainy', 'temperature': 24.0, 'templow': 18.0}]}

Thus, when I try to get the [0]th element of the above I get undefined since it is not actually an array. This becomes an issue on Tileboard as I try to iterate though the first nth elements of the forecast.

Seemingly another user ran into the issue here also : https://community.home-assistant.io/t/need-help-with-recent-daily-weather-forecast-error/759166

Please let me know if I can provide any more information or do any testing for you.

Thanks!

This issue has no "integration causing the issue" hence it's unlikely anyone will look at it. Refile it against whatever weather integration you are using.

Thanks! I refiled and I will close this issue.
