Project 'Gold Medal metrics' doesn't render any data


Hi! I did everything according instructions:
-download package with files
-run npm install
-run npm webpack

Wrote all queries, tested them and tried to open index.html to see results but I saw only HTML without any data (see screenshot)

I tried solution which I found on this forum (Gold medal project - solution code not rendering on localhost) but it also doesn’t work. I downloaded solution code and tried to open it but and it didn’t work.

I was able to open it on localhost: 3001 somehow…

And phrase ’ and follow that with open index.html’ is really confusing because it doesn’t explain anything
