我正在尝试同时使用 Laravel 和 MongoDB。我让他们在未经身份验证的情况下进行交谈，但现在我想添加用户，所以我使用了一些来源和故障排除来汇集：

<?php

namespace App\Models;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
//use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Sanctum\HasApiTokens;

use Illuminate\Database\Eloquent\Model;
use Jenssegers\Mongodb\Eloquent\Model as Eloquent;
use Jenssegers\Mongodb\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use HasApiTokens, HasFactory, Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array<int, string>
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for serialization.
     *
     * @var array<int, string>
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast.
     *
     * @var array<string, string>
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    protected $dates = ['email_verified_at'];
}

但我收到此错误：

请问有什么想法吗？奇怪的是，用户是在我提交帖子时创建的。
