Issue making service calls to RGBW - API error

Configuration
1

hi folks,

I have a RGBW LED strip using the FLUX/LED Integration, and I’m having some API errors, when making certain calls.

I happen to be using Node-RED, but I think the issue is in my syntax.

Here’s what I’m passing the entity, as a service call in NR.

{
    "rgb_color": [
        "{{payload.RValue}}",
        "{{payload.GValue}}",
        "{{payload.BValue}}"
    ],
    "brightness_pct": "{{payload.BrValue}}",
    "white_value": "{{payload.WValue}}"
}

when I pass the following, all is good.

Whereas when I pass this, I get an API error.

How do you call of the white value properly?
