Hi. I am trying to execute quires from the documentation on my local Mongodb replica set with database version 4.2
https://docs.mongodb.com/manual/reference/method/db.collection.updateOne/#example-2

db.students3.updateOne(
   { _id: 3 },
   [
     { $set: { average: { $trunc: [  { $avg: "$tests" }, 0 ] }, lastUpdate: "$$NOW" } },
     { $set: { grade: { $switch: {
                           branches: [
                               { case: { $gte: [ "$average", 90 ] }, then: "A" },
                               { case: { $gte: [ "$average", 80 ] }, then: "B" },
                               { case: { $gte: [ "$average", 70 ] }, then: "C" },
                               { case: { $gte: [ "$average", 60 ] }, then: "D" }
                           ],
                           default: "F"
     } } } }
   ]
)

I get that error (You can see on the screenshoot):

Failed to execute script. Error: the update operation document must contain atomic operators Details: DBCollection.prototype.updateOne@src/mongo/shell/crud_api.js:542:1 @(shell):1:1

But when I execute this query in the mongo CLI or in the console on the documentation site - everything is fine.
