Error with Responsive Images

[homeoftheunits]

Hey Guys,

i got this error:
https://flareapp.io/share/LPdGWzgm#F92

This is my Path Generator:

   /**
     * @param Media $media
     *
     * @return string
     */
    public function getPathForResponsiveImages(Media $media): string
    {
        return sprintf('%s/responsive-images/', $this->buildRootPath($media));
    }

    /**
     * @param Media $media
     *
     * @return string
     */
    private function buildRootPath(Media $media): string
    {
        if ($media->model_type === Application::class) {
            return sprintf('application/%s', Application::find($media->model_id)->uuid);
        }

        if ($media->model_type === Dish::class) {
            return sprintf('dish/%s', Dish::find($media->model_id)->uuid);
        }

        if ($media->model_type === Restaurant::class) {
            return sprintf('restaurant/%s', Restaurant::find($media->model_id)->uuid);
        }

        return md5($media->uuid . config('app.key'));
    }

In Minio i see the Images, and generated Responsive Images. Someone an idea?

Cheers
Ralf
