Problems starting a freshly installed Mean Stack application

I'm trying to start a new mean stack application. However i only get this error when I'm running grunt to start the server:

Have any one encountered this before? Can't find too many other people who have encountered this before.

I was also facing the same error and this info solves it.

"Upgrade to 3.8.23. 3.8.22 introduced better compatibility with mongodb server 3.0 by upgrading to latest version of the driver." credit to vkarpov15 from mongoose Github thread.

What I did was I edit my package.json to upgrade mongoose to "3.8.23". After I edited the package.json I ran npm install and bower install(just to make sure) again and that solved the problem.
