Javascript Sequelize TypeError:无法将未定义或null转换为对象

我正在尝试对SQLServer中的现有数据库使用sequelize模型。当我尝试使用原始查询从表中检索数据时，它会起作用。但当我使用模型时，我会收到以下错误：

Error Occurred TypeError: Cannot convert undefined or null to object

控制器

const Consulta = require('../models/CONSULTAS');

module.exports = {
    async index(req, res) {
        let consulta
        try {
            consulta = await Consulta.findAll({
                where: {
                    seqConsulta: 1
                },
            });
        } catch (e) {
            console.log("Error Occurred", e)
        }

        return res.json(consulta);
    },
};

我也遇到了同样的情况，问题是我忘了在数据库索引中导入我的模型，所以可以尝试以下方法：

const Consulta = require('../app/models/Consulta ');
const models = [ Consulta ];
class Database {
  constructor() {
    this.init();
  }

  init() {
    this.connection = new Sequelize(DataBaseConfig);

    models.map(model => model.init(this.connection));
}
}

const Consulta = require('../app/models/Consulta ');
const models = [ Consulta ];
class Database {
  constructor() {
    this.init();
  }

  init() {
    this.connection = new Sequelize(DataBaseConfig);

    models.map(model => model.init(this.connection));
}
}
