You can control this by specifying the format option, in your case you'd want to set it to false to disable the formatting entirely:

FB_event_id: { type: Types.Number, format: false, required: true, initial: true }

The ObjectId field type isn't what you're after; these are used by the Relationship field type for linking to other documents in the database, and should only be used to store Mongo ObjectIDs. Any other values result in errors.

Personally though, I often use the String field for ID-type fields, it's just as effective as the Number field and reduces the possibility of unexpected behaviour related to parsing numbers in Javascript.
