"Cannot read property 'findAll' of undefined"

Quando tento testar minha rota pessoa estou recebendo o erro "Cannot read property 'findAll' of undefined" Alguem consegue me ajudar ?

people.js

'use strict';
const {
  Model
} = require('sequelize');
module.exports = (sequelize, DataTypes) => {
  class People extends Model {
    /**
     * Helper method for defining associations.
     * This method is not a part of Sequelize lifecycle.
     * The `models/index` file will call this method automatically.
     */
    static associate(models) {
      // define association here
    }
  };
  People.init({
    status: DataTypes.BOOLEAN,
    name: DataTypes.STRING,
    email: DataTypes.STRING,
    role: DataTypes.STRING
  }, {
    sequelize,
    modelName: 'people',
  });
  return People;
};

PeopleController.js

const database = require('../models');

class PeopleController {
    static async ReadAll (req, res) {
        try {
            const allPeople = await database.People.findAll();   
            return res.status(200).json(allPeople);
        }
        catch (error) {
            return res.status(500).json(error.message);
        };
    }
};

module.exports = PeopleController;
