     *
     * @return void
     */
    public function up()
    {
        Schema::create('employees', function (Blueprint $table) {
            $table->id();
            $table->foreignId('user_id')->constrained('users')->restrictOnDelete();
            $table->string('status');
            $table->string('first_name');
            $table->string('last_name');
            $table->string('email')->unique();
            $table->string('contact_number');
            $table->date('date_of_birth');
            $table->string('current_address');
            $table->string('pan_number')->nullable();
            $table->string('bank_account_number')->nullable();
            $table->string('avatar')->nullable();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *

    public function down()
    {
        Schema::dropIfExists('employees');
    }
};

我正在尝试创建一个 API，将员工的个人详细信息存储到数据库中。在这里，图像字段是可选的，因此我在迁移和验证请求中也将头像字段设为可为空。但是，当我尝试将详细信息保存到数据库而不上传图像时，它显示未定义的头像。我不知道这里发生了什么，任何帮助或建议将非常感激。谢谢。

您正在使用字符串值 null 而不是关键字 null。
