如何在带有nestjs、sequelize和postgresql的where子句中使用日期？

import { Injectable } from '@nestjs/common';
import { Sequelize } from 'sequelize-typescript';

@Injectable()
export class DatabaseService {
  private sequelize: Sequelize;

  constructor() {
    this.sequelize = new Sequelize({
      dialect: 'postgres',
      host: 'localhost',
      port: 5432,
      username: 'your_username',
      password: 'your_password',
      database: 'your_database',
    });
  }

  getSequelizeInstance(): Sequelize {
    return this.sequelize;
  }
}

import { Table, Column, Model, DataType } from 'sequelize-typescript';

@Table
export class User extends Model<User> {
  @Column({
    type: DataType.STRING,
    allowNull: false,
  })
  name: string;

  @Column({
    type: DataType.DATE,
    allowNull: false,
  })
  birthdate: Date;
}

import { Op } from 'sequelize';
import { User } from './user.model';

const startDate = new Date('2000-01-01');
const endDate = new Date('2005-12-31');

const users = await User.findAll({
  where: {
    birthdate: {
      [Op.between]: [startDate, endDate],
    },
  },
});
