I tried to reIndex() my mongo collection, but without success.

Thanks for the help guys!


You probably tried this already, but just in case not, does ‘meteor reset’ help?


:smile: yep tried that, not really helping.


I found a simillar problem here. But after reading it, I still couldn’t figure it out. My mongo version is 2.6.7.
I used the collection2 successfully on another project (same local machine and versions)`


The problem was that i am using _id in my simple schema definition:

Schemas.Base = new SimpleSchema
    type: String
    index: true
    unique: true
    regEx: SimpleSchema.RegEx.Id
    autoValue: ->
      if @isInsert
        (if @isSet then @value else
      omit: true
