For anyone else who may have trouble with this…
I’m starting the Back End cert, and I’m using Replit. I had trouble submitting the right URL to fCC. If I just copied and pasted the Replit URL from my browser into fCC, it said that I needed to use a “Live App URL” instead. The phrase occurs nowhere in Replit’s docs. There’s a post in Replit’s forum from a year ago discussing this issue, but their fix doesn’t work anymore.
In order to get that “Live App URL,” here’s what I did:
- I opened the Devtools of Replit’s webview
- I switched to the Console
- I ran the command
console.log(window.location.href);
See picture:
Don’t mind the console.log("hello");, that was me fooling around lol. The important bit is the https://boilerplate-npm--shyaway.repl.co/ part. That’s the “Live App URL,” and fCC did accept that link.
Hope that helps someone else.
