Duplicate key error when creating record

This error is really confusing. I can create record once but second time no matter what, error would appear:

E11000 duplicate key error index: test_db.students.$code_1 dup key: { : null }

This is my schema:

var Schema  = {
    "stuCode" : String,
    "firstName" : Boolean,
    "lastName" : Boolean,
    "email" : String
};

Before I had stuCode as code and _codeand it was required it's unique. That could maybe cause a problem.

I've tried to delete all the data from that collection, remove collection in mongoose.connection.on('open', function(){ }); but the problem is still there. I can only save first record and second one is impossible to save.

What would be the solution for this problem?

Yes that old index on code is probably still there, can't you drop it ?
