Play Lights turns off automatically after setting a scene

[bevrat]

Describe the bug
I have a flow with two hue lights (play) that can be activated. This flow is never executed, its just its existence that trigger the bug. The two lights are part of a group.
When I set (from node-red or from official hue app) a scene for this group, the two light turns off automatically.
I got a debug info from the two hue lights nodes
`status: 429
errors: string

<title>hue personal wireless lighting</title>

  <img src="/hue-color-line.png" class="colorline" />

</div>
<div class="error">Oops, there appears to be no lighting here</div>

` If I remove (or disable) the two lights nodes, everything works fine.

Expected behavior
The lights should stay on
