Experiencing the same error with Kirby 4.0.3 and plugin version 1.0.4

Could it be because of these methods being used:

$file->panelUrl(true)
$file->panelIcon($image)

If anyone needs this, I made a quick-and-dirty fork of the Color Palette plugin that removes the broken Color Extractor functionality but works with Kirby 4 instead: https://packagist.org/packages/tobimori/kirby-color-palette
Not planning to merge this because it just removes functionality but it works for legacy projects.
