Call to a member function store() on array Laravel

I'm trying to store images to the database using this plugin demo, but I get an error Call to a member function store() on array. Can any one help me fix this so I can be able to store images to the database?

I use javascript when submitting the form and on console(request) it shows like category_name: Women fileuploader-list-files: [{"file":"0:/innostudio.de_twitter.png"}] files[]: (binary) files[]: (binary) _token: LZWSXmAbVuIL5HXullJWmJWbJ3wSRU9c9dEtV1cF

Controller

  foreach ($request->files as $photo) {
       $filename = $photo->store('public/photos');
        ProductsPhoto::create([
            'product_id' => $product->id,
            'filename' => $filename
        ]);
    }

Blade

 <input type="file" name="files">
