Mflix App Crashes out of the Box

MongoDB University M220JS: MongoDB for Javascript Developers
#1

Running on Windows 10. The app crashes right our of the box, and it reports that it’s choking on a malformed URI. I tried to run app in step-through debugger, but it never reaches the index.js file in ./src. Hmmm. Stack trace below.

Did you do the whole configuration beforehand? The README file list at a rather lengthy setup that needs to be done.

The error is pointing to a malformed URI in your .env file. Would you mind sharing what you are using there?

I am too getting above error, any solution?
[nodemon] app crashed - waiting for file changes before starting…
npm --version 6.5.0-next.0
node --version v11.6.0

You’ll need to share the connection uri you are using with me in order for me to help!

Thanks. I jumped the gun, expecting the app to standup after the intro video. My mistake.

Would it be helpful if we included a note that the application won’t start until the first bit of configuration is done?

You have a typo error in the user name.

You do not have a password.

I think the requirements asked for a cluster named mflix and yours is call m220. I do not think this is an issue. However, most of the time when it is asked to create something called XXXX you shoud name it XXXX. Some of the test explicitly check for exact name.
