Tell us what’s happening:

I attempted this challenge on GitPod. My work managed to pass test 1, but I stucked at test 2. However, my code did not raised an error when inspecting.


const mongoose = require('mongoose');
mongoose.connect(process.env.MONGO_URI, {useNewUrlParser:true, useUnifiedTopology:true}, function(error){
  if(error){
    console.log(error);
  }else{
    console.log("Success");
  }
});

I think you would need to chain your catch to the connect() to return an error: ```

mongoose.connect('mongodb://127.0.0.1:27017/test').
  catch(error => handleError(error));

Maybe delete the function(error) and try:

const mongoose = require('mongoose');

mongoose.connect(process.env.MONGO_URI, {useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('Success'))
  .catch((error) => console.log(error));

This should handle your error more effectively, especially if the inital connection fails for some reason.

Thank you so much^^ this works well for me.

If the connect method doesn’t work with a callback, you may have updated the Mongoose dependency. I would revert to the initial version in the starting boilerplate to avoid other issues related to API changes (like methods removed).
