MongoDB Enterprise asdf:PRIMARY> db.foo.insert({_id: 1, b: null})

WriteResult({ "nInserted" : 1 })

MongoDB Enterprise asdf:PRIMARY> db.foo.update({_id: 1}, {$inc: {a: 1}})
|
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })

"nUpserted" : 0,

"nModified" : 0,

"writeError" : {

"code" : 14,

"errmsg" : "Cannot apply $inc to a value of non-numeric type. {_id: 1.0} has the field 'b' of non-numeric type null"

}
