db.view.find() breaks with --apiStrict

Spin up a 5.0.0-rc0 server Connect with mongosh or mongo and run the steps below: MongoDB Enterprise replset:PRIMARY> use testdb switched to db testdb MongoDB Enterprise replset:PRIMARY> db.source.insertOne({}) { "acknowledged" : true, "insertedId" : ObjectId("60c088057ddf468ccc60c5e6") } MongoDB Enterprise replset:PRIMARY> db.createView('view', 'source', [{$match: {}}]) { "ok" : 1, "$clusterTime" : { "clusterTime" : Timestamp(1623230493, 2), "signature" : { "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="), "keyId" : NumberLong(0) } }, "operationTime" : Timestamp(1623230493, 2) } MongoDB Enterprise replset:PRIMARY> db.view.find() Error: error: { "ok" : 0, "errmsg" : "BSON field 'aggregate.runtimeConstants' is not allowed with apiStrict:true.", "code" : 323, "codeName" : "APIStrictError", "$clusterTime" : { "clusterTime" : Timestamp(1623230493, 2), "signature" : { "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="), "keyId" : NumberLong(0) } }, "operationTime" : Timestamp(1623230493, 2) } As you can see, the view is trivial and its aggregation not require any unversioned APIs.
