Chaptet 8 - Single-Origin, Multi-Route Proxy, Invalid URL

"use strict";
const path = require("path");
const AutoLoad = require("fastify-autoload");
module.exports = async function (fastify, opts) {
  // Place here your custom code!
  fastify.register(require("fastify-http-proxy"), {
    upstream: "https://news.ycombinator.com/",
  });
  // Do not touch the following lines
  // This loads all plugins defined in plugins
  // those should be support plugins that are reused
  // through your application
  fastify.register(AutoLoad, {
    dir: path.join(__dirname, "plugins"),
    options: Object.assign({}, opts),
  });
  // This loads all plugins defined in routes
  // define your routes in one of these
  fastify.register(AutoLoad, {
    dir: path.join(__dirname, "routes"),
    options: Object.assign({}, opts),
  });
};

With fastify 3.x.x this code above is generated. Paste the custom code and delete the root.js (or uncomment or change the endpoint, whatever...)

@davidmarkclements said:
@reuben158 you've somehow included an invisible zero width non-joiner character, just before the "p" in https, which makes the url invalid.

https://www.fileformat.info/info/unicode/char/200c/index.htm
https://en.wikipedia.org/wiki/Zero-width_non-joiner

I got the same issue and is when we copied the code from that page (Single-Origin, Multi-Route Proxy (1)), VsCode told me "The character U+200c is invisible."

@fcioanca can we please address the hidden characters problem on the learning platform asap

@jhonny111s thanks for that, this will be resolved in a major content update
