Images is trying to post empty objects, add an if statement:

        $image_arr = [];

        foreach(request('images') as $image){
            if($image != null){
                $imagePath = $image->store('uploads', 's3');
                array_push($image_arr, $imagePath);
            }

        };
        return ['Image Array', $image_arr];
