Get Route Parameter Input from the Client - Not Found Error on Route

What’s happening:

I wrote the code for the route, but when I visit it in my browser I get “Not Found” printed on the browser window.

My code so far

const express = require("express");
const app = express();
const homePath = `${__dirname}/views/index.html`;
const assetsPath = `${__dirname}/public/`;
require("dotenv").config();

app.use((req, res, next) => {
  const str = `${req.method} ${req.path} - ${req.ip}`;
  console.log(str);
  next();
});

app.use("/public", express.static(assetsPath));

app.get("/now", (req, res, next) => {
  req.time = new Date();
  req.time += 20000;
  req.time = req.time.toString();
  next()
}, (req, res) => {
  res.json({time: req.time});
});

app.get("/:word/echo", (req, res) => {
  const { word } = req.params;
  res.json({echo: word});
});

app.get("/", (req, res) => res.sendFile(homePath));

app.get("/json", (req, res) => {
  const message = "Hello json";
  const messageUpper = message.toUpperCase();

  if (process.env.MESSAGE_STYLE === "uppercase") {
    res.json({"message": messageUpper});
  } else {
    res.json({"message": message});
  }
});

Challenge: Get Route Parameter Input from the Client

Link to the challenge:

My current REPL

Your form is sending the request to /name.
But there is no route for this.

I was asking about the /:word/echo route. For some reason it wasn’t working earlier even though the code was already correct. It works now but I have no idea what changed.
