Getting a new error in 0.2.31

I see it's from a little recent funkiness of mine:

@Orders = new Meteor.Collection "Orders",
  schema = new SimpleSchema([Cart,
    additionalField:
      type: String
      optional: true
    status:
      type: String
  ])

Guess, you might want to catch this error.

Just for historical lookup, I resolved on my end by fixing the declaration to be

@Orders = new Meteor.Collection("Orders",[Cart,OrderItemsSchema])

OrderItemsSchema = new SimpleSchema
    additionalField:
      type: String
      optional: true
    status:
      type: String

simple-schema is ok with this, and it works.

I added a check to prevent this error, but I can't figure out why it would have happened in the first place. There shouldn't be any difference between the handling of your initial syntax and your fix.

[aaronjudd]

Not sure, but I was having other issues with the first syntax working (on insert it was only inserting the id), and I prefer the second method anyhow, so it's all good. It's here for posterity.

Had the same error. I had 2 quickforms with the same id. Ounce I solved that issue I was good to go.

EDIT: not the same error but the same TypeError. So for posterity: check if you have 2 Quickforms with same id.
