Home Assistant API - color_temp

1

I try to change the temperature through the color_temp property, but the API returns Status: 400 [Bad request]. If I remove such attribute from the JSON, there is no problem in changing the brightness or color.

Could you tell me how to use this property correctly?

Thanks

I was able to set it via POST /services/scene/apply:

{
    "entities": {
        "light.bedroom_temperature_light": {
            "state": "on",
            "color_temp": 250
        }
    }
}
