Question

我已经在 Heroku 上成功部署了一个 PERN 堆栈。该应用程序在本地完美运行，但在部署时无法连接。它运行静态页面，但没有连接到 API。

错误是我收到 500 内部服务器错误。我为客户端连接 localhost:3000，为服务器连接 localhost:3001。我正在使用代理来替换我的路由的 baseURL。我已经为 Heroku 插件设置了 DATABASE_URL。同样在部署过程中，我在部署前在 Heroku 中创建了必要的表。

我曾多次尝试部署并寻找解决方案，但都没有成功。任何帮助将不胜感激。

错误：

Failed to load resource: the server responded with a status of 500 (Internal Server Error)
main.28345b5c.chunk.js:1 Error: Request failed with status code 500
    at e.exports (2.09b0e732.chunk.js:2)

DB.js：

const devConfig = `postgresql://${process.env.PG_USER}:${process.env.PG_PASSWORD}@${process.env.PG_HOST}:${process.env.PG_PORT}/${process.env.PG_DATABASE}`;

const proConfig = process.env.DATABASE_URL; //heroku addons

const pool = new Pool({
  connectionString:
    process.env.NODE_ENV === 'production' ? proConfig : devConfig,
});

module.exports = pool;

Server.js：

require('dotenv').config();
const cors = require('cors');
const db = require('./db');
const express = require('express');
const app = express();
const path = require('path');
const morgan = require('morgan');
const { validateData } = require('./utils/validators');
const port = process.env.PORT || 3001;
app.use(express.json());
app.use(morgan('dev'));
app.use(cors());

if (process.env.NODE_ENV === 'production') {
//server static content
//npm run build
app.use(express.static(path.join(__dirname, 'client/build')));
}

app.get('/api/v1/restaurants', async (req, res) => {
