我试图sequelize使用以下用户模型对我的测试数据库执行数据库迁移，作为参考，之前也进行过迁移。

const User = Sequelize.define('user', {
    user_id: {
        type: sequelize.STRING,
        primary_key: true,
    },
    firstName:{
        type: sequelize.STRING,
        allowNull: false
    },
    lastName:{
        type: sequelize.STRING
    },
    dob:{
        type: sequelize.DATE
    },
    birth_time:{
        type: sequelize.TIME,
        allowNull: true
    },
    gender:{
        type: sequelize.ENUM,
        values: ['male', 'female']
    }
});

但是，在执行此操作时，一旦执行了一些数据库查询，我就会收到以下错误。

我确实遇到过这样的情况，我在同一个命名空间中有 3 个 pod。让我们打电话给他们aaa，bbb和ccc。

同时 NetworkPolicies 设置在其中 2 个中的每一个中以接受和转发流量，假设netpolfor aaaisnpa和 for bbbisnpb

我的问题是如何ccc允许流量仅从aaa并且bbb仅通过配置 pod 和现有网络策略进入
