Tell us what’s happening:
I think my code is right? But it keeps error.

let express = require('express')
let app = express()

// console.log('Hello World')

// app.use((req, res, next) => {
//   let string = req.method + " " + req.path + " - " + req.ip
//   console.log(string)
//   next()

hello and welcome to fcc forum :slight_smile:

  • you are attempting to extract “word” from “req.params.word”, which is wrong!!

consider this code from example

req.params: {userId: ‘546’, bookId: ‘6754’}

  • where userId and bookId is “destructured” from? you are supposed to do that with “word” as well

happy learning :slight_smile:
