Cannot read property 'prototype' of undefined - node.js

Question

I'm starting with Parse and Node.js. I'm trying to retrieve data from Parse db and I don't manage to.
var Parse = require('parse').Parse;
Parse.initialize("*************", "*****************");
module.exports = {
index: function(req, res, next){
var query = new Parse.Query(Parse.Event);
query.find({
success: function(results) {
console.log(results);
},
error: function(error) {
console.log(error.message);
}
});
}
}
And I got this error :
TypeError: Cannot read property 'prototype' of undefined

Can someone help me please ?

There is a fix listed in the comments, but the actual problem here is that you're treating a user-defined class "Event" like a Parse class.
change
var query = new Parse.Query(Parse.Event);
to
var query = new Parse.Query("Event");
