这里是我的UserFactory：

<?php

namespace Database\Factories;

use App\User;
use Faker\Generator as Faker;
use Faker\Factory as FakerFactory;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;

$factory->define(User::class, function (Faker $faker) {
    static $password;

    return [
        'firstname' => $this->faker->firstName(),
        'name' => $this->faker->lastName,
        'nickname' => $this->faker->userName,
        'email' => $this->faker->unique()->safeEmail,
        'password' => $password ?: $password = bcrypt('secret'),
        'remember_token' => Str::random(10),
    ];
});

这里是我的用户模型的第一部分：

class User extends Authenticatable implements HasLocalePreference
{
    use Notifiable;
    protected $table = 'users';
    protected $appends = ['avatar','targetLang','targetLangId','type', 'isAdmin'];
    protected $casts = [
        'preferences' => 'array',
    ];

    protected $guarded= [];

    protected $hidden = [
        'password', 'remember_token','accessToken','refreshToken',
    ];

还有我调用工厂的测试：

class MoveCourseItemTest extends DuskTestCase
{
    /**
     * A Dusk test to move card in other block.
     *
     * @return void
     */
    public function testMoveCard() {

        // Create Teacher User
        $teacher = factory(User::class)->create([
            'isTeacher' => 1,
            'termsofuse_id' => 1,
            'privacypolicy_id' => 1,
        ]);

最后，我得到了这个错误，只在staging环境中（而不是在本地环境中）：
Illuminate\Database\QueryException：SQLSTATE[HY000]：一般错误：1364 1364 Field 'firstname' doesn't have a default value（SQL：插入到users（name，email，password，remember_token，isTeacher，termsofuse_id，privacypolicy_id，updated_at，created_at）值（Kenneth Altenwerth Jr.，koch.库珀example.org，$2y$10$1B7LlTzM4iINkVI/82Pp6OHSUWBWaePpdDKMy1DRW2K02d8UYKc2S，r0WnPBrZGG，1，1，1，2021-07-29 21：12：54，2021-07-29 21：12：54））
有谁知道我该怎么解决？谢谢！
