Aggregation fails with ambiguous assertion when applied to a collection with forbidden BSON types

    • Type: Icon: Improvement Improvement
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • 2.1.1
    • Affects Version/s: 2.1.0
    • Component/s: Aggregation Framework
    • None
    • Fully Compatible

      If you run aggregate on a collection containing one of the following fields

      • MinKey
      • MaxKey
      • EOO
      • Undefined
      • DBRef
      • Code

      Example:

      > db.foo.insert( { x : MinKey } )
      > db.foo.find()
      { "_id" : ObjectId("4f3ad5dc7302cfae80686b02"), "x" : { $minKey : 1 } }
      > db.foo.aggregate( { $project: { x : 1 } } )
      {
      	"errmsg" : "exception: assertion src/mongo/db/pipeline/value.cpp:183",
      	"code" : 0,
      	"ok" : 0
      }

      This error will happen if an illegal type is in any of the documents passed into aggregation. Should be documented and improve the error message.
