Tell us what’s happening:

i created a
MongoDB cluster at

added a MONGO_URI with
my URL as Value


yes i replaced

changed source at the app.js

mongoose.connect(MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true });

and also tried

let mongoose = require('mongoose');
mongoose.connect(MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true });

was cloning the GitHub source to my repl and pressed run

and gut this error:

i got error:

Error: Cannot find module ‘/home/runner/boilerplate-project-urlshortener/index.js’

Link to the challenge:

Please post a link to your replit.

Did you use the Replit starter project referenced in the challenge instructions?

its from

You need to show hidden files by clicking on the 3 vertical dots and then open the .replit file and change index.js to server.js, because the app uses server.js as the entry point.

Once you fix that and click Run, you will get an error message that I believe you can easily fix.

thanks i changed.

now i get other error:

ReferenceError: MONGO_URI is not defined
at Object. (/home/runner/boilerplate-mongomongoose/myApp.js:4:18)

but i added it in the Secrets (without ’ or " )

I see:

mongoose.connect(MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true });

I do not see where you defined a variable in your code named MONGO_URI. That is why you are getting the error. Look carefully at the example in the instructions on referencing the environment variable named MONGO_URI.

its in the Secrets tab.

In the previous curriculum section, do you not remember how to reference an environment variable? If not, I would review the previous app created, to see how you did it there.

The problem is not in the Secrets section. You are doing that correctly. The problem is how you are trying to reference that environment variable in the code.

ahhh yes. ists not referenzed. seems i forgot it

No you did not. I just looked at your replit for the Express challenges and you did it correctly in your GET /json route.

thanks and sorry :pray:

one of my problems is that i often mix to many program-styles and languages in my mind. and i usually use jetbrains - tools :wink: its nearly like a auto-correction-tool
