I do not see that
I see an error when running tho:
DB Connection Error: The uri parameter to openUri() must be a string, got “undefined”. Make sure the first parameter to mongoose.connect() or mongoose.createConnection() is a string.
I can’t help you as I have no experience with mondodb
I don’t have much experience with the challenge you linked but from network standpoint you are getting a 404 error (the network screenshot )
The server in glitch It’s not able to identify your URL.
There might be a small typo or something have you checked for those ?
