App crashes when invalid insert

I've just cloned this project and did nothing but establishing my mongodb_uri and then I wanted to try it locally. It works perfectly but when I make an insert (from the webpage) without any value for first and last name the server crashes and the insertion to mlab is made (empty fields). How do I prevent this?

This is the error I get:

ERROR: Invalid user input
/Users/nanop/Desktop/mean-contactlist/node_modules/mongodb/lib/utils.js:98
    process.nextTick(function() { throw err; });
                                  ^
