Nodejs - UnhandledPromiseRejectionWarning: TypeError:无法将未定义或null转换为object

我有以下几点
SessionController.js
import User from '../models/User';
class SessionController {
async store(req, res) {
const { email, password } = req.body;
console.log(req.body);
const user = await User.findOne({ where: { email } });
}
}
export default new SessionController();
User.js
import Sequelize, { Model } from 'sequelize';
import bcrypt from 'bcryptjs';
class User extends Model {
static init(sequelize) {
super.init(
{
name: Sequelize.STRING,
email: Sequelize.STRING,
password_hash: Sequelize.STRING,
},
{
sequelize,
}
);
return this;
}
checkPassword(password) {
return bcrypt.compare(password, this.password_hash);
}
}
export default User;
和失眠从/sessions路由发送数据
我调用console.log(req.body)并获得所有数据，所以我不知道为什么会得到这个错误：
(node:8589) UnhandledPromiseRejectionWarning: TypeError: Cannot convert undefined or null to object
at Function.keys (<anonymous>)
at Function.findAll (/home/julio/www/bootcamp2019/gympoint/node_modules/sequelize/lib/model.js:1692:47)
at Function.findOne (/home/julio/www/bootcamp2019/gympoint/node_modules/sequelize/lib/model.js:1924:17)
at store (/home/julio/www/bootcamp2019/gympoint/src/app/controllers/SessionController.js:10:41)......有什么想法吗？

同样的问题也发生在我身上。
我能够发现我有一个错误的数据库路径，您可以在第4行和第5行看到。
import express from 'express';
import routes from './routes';
// import './config/database'; (Wrong)
import './database'; // (Correct)
class App {
constructor() {
this.server = express();
this.middlewares();
this.routes();
}
middlewares() {
this.server.use(express.json());
}
routes() {
this.server.use(routes);
}
}
export default new App().server;

将异步函数的等待调用放在try/catch块中。
import User from '../models/User';
class SessionController {
async store(req, res) {
try {
const { email, password } = req.body;
console.log(req.body);
const user = await User.findOne({ where: { email } });
} catch (e) {
console.log("Error Occurred", e)
}
}
}
