Hello,
I had some problems with a Ansible Module I’ve created for MongoDB and I think I’ve found a possible issue in 4.4.X
The docs detail the format for the config.tags collection…
{
"_id" : { "ns" : "records.users", "min" : { "zipcode" : "10001" } },
"ns" : "records.users",
"min" : { "zipcode" : "10001" },
"max" : { "zipcode" : "10281" },
"tag" : "NYC"
}
But in MongoDB 4.4.6 It seems to be the following. Note the value for _id…
{ "_id" : ObjectId("60e2e7cff7c9d447440bb114"), "ns" : "records.users", "min" : { "zipcode" : "10001" }, "max" : { "zipcode" : "10281" }, "tag" : "NYC" }
Raw output from my tests…

This doesn’t happen when I tests with 4.2.14

Records are added using updateZoneKeyRange with Python/pymongo
