Solution validation thru my server does not work

Tell us what’s happening:
I’ve forked the repo and host it on my server in order to validating my solutions. I just started out the APIs and Microservices Certification and I’m at the 1st lesson (Managing Packages with Npm - How to Use package.json, the Core of Any Node.js Project or npm Package).
I tried to validate my solution at:, which should validate since it’s a very basic addition of a field name in the package json.

Your code so far
“name”: “fcc-learn-npm-package-json”,
“author”: “Chinh Le”,
“dependencies”: {
“express”: “^4.14.0”
“main”: “server.js”,
“scripts”: {
“start”: “node server.js”
“engines”: {
“node”: “8.11.2”
“repository”: {
“type”: “git”,
“url”: “https://idontknow/todo.git

Challenge: undefined

Link to the challenge:

You can’t just submit the package.json it has to be the full page. Looking at the “Page Not Found” it looks like Netlify and you can’t use Netlify (at least not out of the box) as you have to use Node/Express.

I don’t really know much about serverless functions but maybe that is something you can look into.

Or just use Glitch for the curriculum.

thank you much appreciated!
