_ensureIndex causes crash

[cunneen]

If the collection I'm stubbing has a call to _ensureIndex (as per How to optimize your Mongo database for Meteor.js , I get the following error

Uncaught Error: Can only call _ensureIndex on server collections

at Mongo.Collection._ensureIndex (packages/mongo/collection.js:651:11)

Hello,

I had the same issue, you should check whether you invoke this function on the server or on the client side. It must be invoked on the server side.

Meteor.startup( () => {
  SomeCollection._ensureIndex({
    "_id": 1
  });

  SomeCollectionTwo._ensureIndex({
    "_id": 1
  });
});

this is my perfectly working collectionIndex.js file, it is under
../imports/startup/server/collectionIndexes/ folder.

I hope this helps.

Cheers.

Thanks! I've actually no recollection of posting the above issue.
