PV power production forecast with method Solar.Forecast service do not work

[overas]

EMHASS add-on v0.4.2 Home Assistant 2023.10.3

When I use the method=solar.forecast with the parameter "solar_forecast_kwp":5 I get an error. When I use method=scrapper everything is working.

rest_command:
  trigger_tibber_forecast:
    url: http://localhost:5000/action/dayahead-optim
    method: POST
    content_type: "application/json"
    timeout: 300

      "prod_price_forecast":{{((state_attr('sensor.energy_price_toraldasen_32', 'raw_today') | map(attribute='total') | list  + state_attr('sensor.energy_price_toraldasen_32', 'raw_today') | map(attribute='total') | list))[now().hour:][:24]}},
      "def_total_hours":{{states('sensor.list_operating_hours_of_each_deferrable_load')}},
      "solar_forecast_kwp":5
      }
