当试图传路径图像数据库，我得到这个错误"创造默认对象从空值"

我继续得到这一错误的"创建默认对象从空值"每当我尝试上传资料图片时，注册用户，是我想要做的是上传来的影像路径"profile-photos/PP_1637044275.jpg"数据库，没有图像的名称、任何帮助，将不胜感激。

这是控制器/操作类

  class CreateNewUser implements CreatesNewUsers
 {
    use PasswordValidationRules;

  /**
 * Validate and create a newly registered user.
 *
 * @param  array  $input
 * @return \App\Models\User
 */
public function create(array $input)
{

    $request = request();

    //Handle profile photo Upload
    if ($request->hasFile('photo')) {
        // Get filename with extention 
        $filenamewithExt = $request->file('photo')->getClientOriginalName();
        // Get just filename
        $filename = pathinfo($filenamewithExt, PATHINFO_FILENAME);
        // Get just Extention
        $extention = $request->file('photo')->getClientOriginalExtension();
        // Filename to store
        $filenameToStore = $filename.'_'.time().'.'.$extention;
        // Upload Image
        $path = $request->file('photo')->storeAs('profile-photos', 
        $filenameToStore);

        $user = new User;
        $user->profile_photo_path = $path;
       

    }

    
 
    if ($request->hasFile('photo')) {
        
        $user->profile_photo_path = $path;
  
       
    }
