Alexa hue emulation error

Hi ,

I am working with ws2812b led strip to change the color of the led strip using alexa

I have exposed my item as :

Color LEDStrip_FF_Kitchen_Cabinet_1_Color “daksh” (FF_Kitchen,gLEDStrip_Kitchen_Color) [ “ColorLighting” ]

Sitemap as :

Color LEDStrip_FF_Kitchen_Cabinet_1_Color “daksh” (FF_Kitchen,gLEDStrip_Kitchen_Color) [ “ColorLighting” ]

Alexa is able to discover the device but on the top it says (Device doesn’t support requested value).

The leds are functional using the app when i click on the color basic color(rgb) the device works fine and gives no error the leds too are changing its color.

The problem comes when i ask alexa to change the color of the strip other than red,blue,green.Alexa changes the color of the strip but makes the device malfunction along with an announcement that the device is malfunctioning.

Please can anyone help me with this.

Thanks,
