Meteor JS - Manque un lien de ou vers mongo

Bonjour,

Je débute avec l'appli leaderboard qui est dèja auto-configurée.
Lorsque je transfère le codage vers les trois piliers : /main.css /main.html /main.js
d'un autre projet vide , mongo n'est pas reconnu.

Console meteor mongo : un player est actif
Code:

1 2 meteor:PRIMARY> db.Players.find(); { "_id" : ObjectId("5ed371b8d17447be23863859"), "name" : "David", "score" : 0 }
main.js :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Players = new Mongo.Collection("players"); ... // On server startup, create some players if the database is empty. if (Meteor.isServer) { Meteor.startup(function() { if (Players.find().count() === 0) { var names = ["Ada Lovelace", "Grace Hopper", "Marie Curie", "Carl Friedrich Gauss", "Nikola Tesla", "Claude Shannon" ]; _.each(names, function(name) { Players.insert({ name: name, score: Math.floor(Random.fraction() * 10) * 5 }); }); } }); }
Au démarrage, le niveau server de mongo ne démarre pas !

La console js ne donne pas d'erreur spécifique :
