Mongolab and Mongoose Not connecting [duplicate] - node.js

Question

MongoDB just forced an update on my Heroku server today from 2.6 to 3.0
Now my app crashes shortly after startup with the error:

I checked their status page, and found that Mongo had updated their servers to version 3.0, but also that the update should be stable now, and thus is something I need to do on my end.
After looking a bit more into it. I figured out that I'm supposed to install new "drivers" to be compatible with version 3.0.
I found this link http://docs.mongodb.org/manual/release-notes/3.0-scram/#upgrade-drivers
But it doesn't describe how exactly I can go about updating the drivers on my Heroku app.
I'm using their sandbox servers.
I tried contacting their support but they just gave me the same link.
I contacted Heroku support as well. But all they said is:
You need to make sure that the libraries you are using for Mongo
support the new version 3.0 of Mongo. It's not necessarily a 'driver'
as such
Which doesn't help me either.
Here's the contents of my package.json if that helps.

Any help to figure out how I can update drivers on my Heroku app to be compatible with the new 3.0 MongoDB would be greatly appreciated.

Answer 1

You're using mongoose 3.8.19. The latest version of mongoose is 4.1.9. I would start there:
$ npm install --save --save-exact mongoose#4.1.9

Answer 2

I had the exact same problem
I did all of the above and nothing worked. Only until I deleted mongoose out of my package.json and reinstalled it thats when it worked
