How to fix the Express req.body undefined error

 Now, if we send a JSON data to the /users route, we will see an undefined in the console.

To fix this error, first we need to parse our incoming requests by using the express.json() , express.urlencoded() middleware functions.

const express = require(“express”);
const app = express();

// middleware
app.use(express.urlencoded());“/users”, (req, res) => {

app.listen(3000, () => console.log(`App is running`));
