I've made a simple Three.js animated scene which exports a GLB file successfully, and I'm now attempting to include the option to export a GIF of the object. I'm using the omggif repository. I'm getting a 'Invalid code/color length, must be power of 2 and 2 .. 256.' error, and when I log the palette array it's empty. So I presume the problem is more that I'm passing something in incorrectly. I don't know if deciphering this would be easier than finding another option. Any suggestions or guidance would be appreciated.

    var palette = opts.palette;
    if (palette === undefined || palette === null) {
      using_local_palette = false;
      palette = global_palette;
    }

    if (palette === undefined || palette === null)
      throw new Error("Must supply either a local or global palette.");

    var num_colors = check_palette_and_num_colors(palette);

  function check_palette_and_num_colors(palette) {
    var num_colors = palette.length;
    if (num_colors < 2 || num_colors > 256 ||  num_colors & (num_colors-1)) {
      throw new Error(
          "Invalid code/color length, must be power of 2 and 2 .. 256.");
    }
    return num_colors;
  }
