在按日期排序中使用Op.between时出现TypeScript错误

我想在一个MySql表中查找在某个日期范围内创建的所有记录。
于是我写道：

import { Sequelize, Model, DataTypes, Op } from 'sequelize';

const sequelize = new Sequelize({
  // some db connection config
  dialect: 'mysql'
})

class Patient extends Model {
  public guid!: number;
  public name!: string;

  public recordState: number = 0;
  public createdAt?: Date;
  public updatedAt?: Date
}
Patient.init({
  guid: {
    type: DataTypes.STRING,
    primaryKey: true,
    allowNull: false
  },
  name: { type: DataTypes.STRING, allowNull: false },

  recordState: {
    type: DataTypes.INTEGER,
    allowNull: false,
    defaultValue: 0
  },
  createdAt: DataTypes.DATE,
  updatedAt: DataTypes.DATE
}, {
  sequelize,
  modelName: 'Patient',
  timestamps: false
})

Patient.findAll({
  where: {
    createdAt: {
      [Op.between]: [new Date('2020-02-02'), new Date()]
    }
  }
})

但是，当我尝试用tsc编译它时，它报告了如下错误：

sequelize.ts:50:5 - error TS2322: Type '{ [between]: Date[]; }' is not assignable to type 'string | number | boolean | WhereAttributeHash | AndOperator | OrOperator | Literal | Where | Fn | Col | WhereOperators | Buffer | WhereGeometryOptions | (string | ... 2 more ... | Buffer)[]'.
  Types of property '[Op.between]' are incompatible.
    Type 'Date[]' is not assignable to type 'string | number | boolean | [number, number] | WhereAttributeHash | AndOperator | OrOperator | Literal | Where | ... 5 more ... | (string | ... 2 more ... | Buffer)[]'.
      Type 'Date[]' is not assignable to type '(string | number | WhereAttributeHash | Buffer)[]'.
        Type 'Date' is not assignable to type 'string | number | WhereAttributeHash | Buffer'.
          Type 'Date' is not assignable to type 'WhereAttributeHash'.
            Index signature is missing in type 'Date'.

50     createdAt: {
       ~~~~~~~~~

Found 1 error.

看起来我不能用带日期范围的Op.between，但是我用JS写了类似的代码就可以了。
所以我想知道我的TS代码中是否真的有问题，或者只是类型定义中缺少了一个，或者不推荐使用带日期的Op.between？

您正在传递一个日期对象而不是字符串。请执行以下操作：

Patient.findAll({
  where: {
    createdAt: {
      [Op.between]: [new Date('2020-02-02').toISOString(), new Date().toISOString()]
    }
  }
})

在我情况下，我有：

createdAt: {
        [Op.between]: [
          new Date(startDate).toISOString(),
          new Date(`${endDate} 23:59:59`).toISOString()
        ]
      }

并努力变更为：

createdAt: {
        [Op.and]: [
          {
            [Op.lt]: new Date(`${endDate} 23:59:59`),
            [Op.gt]: new Date(startDate)
          }
        ]
      }
