嗨，当我尝试在邮递员中更新图像时出现错误

我的控制器

   $validator =    Validator::make($request->all(), [
    'category_id'=> 'required',      
    'product_name'=> 'required', 
    'product_description'=> 'required',      
    'product_img'=> 'required' 
 ] );
    if ($validator -> fails()) {
        return $this->sendError('error validation', $validator->errors());
    }
    $product = Product::findOrFail($id) ;

    $product->category_id = $request->input('category_id');
    $product->subcat_id = $request->input('subcat_id');
    $product->product_name = $request->input('product_name');
    $product->product_description = $request->input('product_description');
    $product->product_properties = $request->input('product_properties');
    $product->product_img =  $request->file('product_img')->store('images');
    $product->product_pdf =  $request->file('product_pdf')->store('files');
    if($product->update()){
        return $this->sendResponse($product->toArray() , 'Product Updated Succesfully');
    }

我的邮递员行

"product_img":"Downloads/screencapture-file-C-Users-gkpro-Desktop-ui-Semantic-UI-master-examples-navbar-html-2019-01-03-20_31_47.png"

我收到这个错误

在 null 上调用成员函数 store()

大家，我需要将图像名称保存在数据库的头像列中，并将图像保存在 public/Storage/users 我的代码这里 将图像链接保存在数据库中，请帮忙。

public function handleProviderCallback($service)
{
    $user = Socialite::driver($service)->user();
    $FindUser = User::where('email',$user->getEmail())->first();
        if($FindUser){
            Auth::login($FindUser);
        }
        else{
            $NewUser = new User;
            $NewUser->email = $user->getEmail();
            $NewUser->name  = $user->getName();
            $NewUser->avatar  = $user->getAvatar();
            $NewUser->password  = bcrypt(123456);
            $NewUser->save();
            Auth::login($NewUser);
        }
    return redirect('/');
}
