Heroku app crashes after MongoDB updated to 3.0

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:

2015-10-01T10:22:27.         


        

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
