如何向grpc返回sequelizejs的结果列表？

// 服务端代码
const grpc = require('grpc');
const protoLoader = require('@grpc/proto-loader');
const Sequelize = require('sequelize');

// 加载protobuf文件
const packageDefinition = protoLoader.loadSync('path/to/your/proto/file.proto');
const protoDescriptor = grpc.loadPackageDefinition(packageDefinition);
const yourService = protoDescriptor.yourService;

// 创建Sequelize实例
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql',
});

// 定义模型
const User = sequelize.define('user', {
  name: Sequelize.STRING,
  age: Sequelize.INTEGER,
});

// gRPC服务端方法
function getUsers(call, callback) {
  User.findAll().then(users => {
    const userList = users.map(user => ({
      name: user.name,
      age: user.age,
    }));
    callback(null, { users: userList });
  }).catch(error => {
    console.error('Error:', error);
    callback(error);
  });
}

// 创建gRPC服务器
const server = new grpc.Server();
server.addService(yourService.YourService.service, { getUsers });
server.bind('localhost:50051', grpc.ServerCredentials.createInsecure());
server.start();

// 客户端代码
const grpc = require('grpc');
const protoLoader = require('@grpc/proto-loader');

// 加载protobuf文件
const packageDefinition = protoLoader.loadSync('path/to/your/proto/file.proto');
const protoDescriptor = grpc.loadPackageDefinition(packageDefinition);
const yourService = protoDescriptor.yourService;

// 创建gRPC客户端
const client = new yourService.YourService('localhost:50051', grpc.credentials.createInsecure());

// 调用服务端方法
client.getUsers({}, (error, response) => {
  if (error) {
    console.error('Error:', error);
    return;
  }
  console.log('Users:', response.users);
});
