Node-red-contrib-huemagic problems

Last few days my node red contrib huemagic has been very unstable. In the debug window I see the following error appear very often when I trigger a scene:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
    <title>hue personal wireless lighting</title>
    <link rel="stylesheet" type="text/css" href="/index.css">
</head>
<body>
    <div class="philips-header">
      <img src="/philips-blue.png" class="philips-logo" alt="Philips" />
    </div>
    <div class="header">
      <img class="header-logo" src="/hue-logo.png" alt="hue personal wireless lighting" />

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

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

If I trigger the scene a second later sometimes I works without an issue. This happens all the time with any room, and any scene. Does anybody have an idea what could be wrong?
Today I have already moved 15 lights from my Hue bridge to Deconz, because I thought my bridge might have been full, but the problem didn’t go away.

Did you ever get anywhere with this issue?

I have it also, two lights fail in one flow, but they work in others. Same error message as you, and triggering the flow later on doesn’t have an issue, and the lights work as expected.
