Please help with script syntax on template

Tags: #<Tag:0x00007f77ff943cb0>

Would you please review the following syntax and tell me how I can make it work? I don’t get any errors on the log when I trigger it but it is not working.

alexa_wakeup:
  alias: Alexa Wake Up Message
  sequence:
  
  - service: notify.alexa_media
    data_template:
      target:
        -media_player.alexa_dot_bedroom
      data:
        type: tts
      message: ->
        {%- set temp = states("sensor.irrigation_temperature") | int -%}
        {%- set hum = states("sensor.irrigation_humidity") -%}

        {%- if temp > 0 -%}
          
          '{{ ["Buenos dias.","Good morning","Rise and Shine"] | random }} The time is {{ states("sensor.time") }} the temperature outside is {{ temp }} degrees. The humidity is {{ hum }} percent.'
     
        {%- else -%}

          '{{ ["Buenos dias","Good morning","Rise and Shine"] | random }} The time is {{ states("sensor.time") }} the temperature outside is {{ state_attr("weather.dark_sky","temperature") }} degrees. The humidity is {{ state_attr("weather.dark_sky","humidity") }} percent.'
     
        {%- endif -%}
