DOCSP-10021 describe the basic steps followed on Atlas to upgrade from a replica set to a sharded cluster. SERVER-47701 adds a test to ensure this process works, however, the mapreduce and aggregation commands with output don't work when connected to the primary MongoD directly, they fail with a similar error:
uncaught exception: Error: command failed: {
"operationTime" : Timestamp(1589285086, 3),
"ok" : 0,
"errmsg" : "MapReduce internal error :: caused by :: don't know dbVersion for database test",

}
And it looks like it fails while doing a listCollections:
