        $originalExtension = strtolower(pathinfo($originalName, PATHINFO_EXTENSION));

It seems like pathinfo($originalName, App\Services\Upload\PATHINFO_EXTENSION) can also be of type array; however, parameter $string of strtolower() does only seem to accept string, maybe add an additional type check?

        $originalBasename = pathinfo($originalName, PATHINFO_FILENAME);

The assignment to $originalBasename is dead and can be removed.

        $slugger = new AsciiSlugger();

        $filename = mb_strimwidth($slugger->slug($object->getDepartment()->getName() ?? 'unknown'), 0, 16);

        $filename .= '_'.mb_strimwidth($slugger->slug($object->getProjectName()), 0, 16);

        $filename .= '_'.date('ymd-His');

        $filename .= '_'.bin2hex(random_bytes(5));

        //Add original extension
        $filename .= '.'.$originalExtension;

        return $filename;
    }
