Setting Light hex color not working (400 bad request)

[GRX]

Describe the bug I've updated huemagic to 4.2.2 and now my flow is failing. There are 2 lights that change color every hour using the following msg.payload:

msg.payload = {
    hex: "b387ff"
}

return msg;

Since the last update, this (or any other color/rgb: [255, 255, 255]/etc) results in a 400 - Bad request. Even the alert does not working anymore.

Flow to Reproduce

1. Update to 4.2.2
2. Create a payload using a function block
3. Send payload including hex/rgb to the destined light
4. Observe debug window/logs

Expected behavior The light to change to specified color

Please complete the following information:

• Node-RED version: 2.2.2

• Device running Node-RED: Docker on Raspberry Pi 4 Model B

Hi @GRX, are the affected bulbs original Signify / Hue ones?

[GRX]

Hi, Yes, this affects all bulbs. I have Ikea bulbs as original Signify/Hue bulbs and spots and none of them seem to work.

However; I've converted the Hex colors to XY, because colorXY seems to be working :)

How to convert hex to colorXY?

How to convert hex to colorXY?

You can use This tool, set the Input system to Hex. Once you've pasted the Hex color, you can use the first 2 coordinates at XYZ (so XY) to use in your payload.

XY colors are the actual way to send them to the lamps, since HUE changed the API. The RBG / hex values in HueMagic just got actually translated into XY.

To run it reliable, I recommend to use only XY colors.
