Can not build, npm ERR!

1

Hi, need help. Deploy failed on build, very strange “cors” issue npm ERR! Cannot read property ‘cors’ of undefined. I pressed “clear cache” and deploy, nothing helped. Have no idea.

import express from 'express';
import cors from 'cors';
import { router as productsRouter } from './routes/products';

const router = express.Router();
const port = 5000;
const app = express();

app.use(cors());

    "start": "node ./build/server.js",
    "build": "npm ci && tsc",

Hey,

It looks like you have an opened support ticket with us and that your issue was resolved by installing your dependencies before you start the app. Let’s keep the conversation there to avoid any duplicates.

Regards.
Jérémy, Render Support
