      A minimal repro for $bucket:

      > db.t.insert({a: 1, b: 2})
> db.t.aggregate([{$bucket: {"groupBy": {$and: ["$a", 2]}, boundaries: [0, 1], default: 1}}])

      Notice that $bucket without an $and for the groupBy does not produce the error and group can be pushed down and executes correctly,

      db.t.aggregate([{$bucket: {"groupBy": "$a", boundaries: [false, true], default: 1}}])

      A minimal repro for $sortByCount:

      > db.t.aggregate([{$sortByCount: {$and: ["$a", 1]}}])
