MongoInvalidArgumentError: Update document requires atomic operators

I am going through a course on MongoDB. Below is my list of documents in a collection called 'flightData'. Below is result of find query:

flights> db.flightData.find()
[
  {
    _id: ObjectId("611aaa1c4a0269583c8d81b0"),
    aircraft: 'AirBus A308',
    departingFrom: 'Mumbai',
    arrivalStation: 'Moscow',
    departureDate: '24/09/2021',
    departureTime: '01:44',
    arrivingAt: '12:00',
    isOneWay: false,
    status: {
      description: 'on time',
      lastUpdated: 'One hour ago',
      details: { contact: 'John Doe' }
    }
  },
  {
    _id: ObjectId("611aaa554a0269583c8d81b1"),
    aircraft: 'AirBus A308',
    departingFrom: 'Kolkata',
    arrivalStation: 'Stockholm',
    departureDate: '24/09/2021',
    departureTime: '01:44',
    arrivingAt: '12:00',
    isOneWay: false,
    status: {
      description: 'on time',
      lastUpdated: 'One hour ago',
      details: { contact: 'Cool User' }
    }
  }
]

When they show the difference between update and updateMany through an example similar to below one:

flights> db.flightData.update({_id:ObjectId("611aaa554a0269583c8d81b1")},{"delayed":false})

In the lecture it works. However, in my case it throws below error:

MongoInvalidArgumentError: Update document requires atomic operators

Can someone please explain this behavior? Is it not supported for my version or something else?

I am using MongoDB 5.0.2, mongosh 1.0.5

If you want to add the "delayed" field to the document you will want to use the $set operator

db.flightData.update({_id:ObjectId("611aaa554a0269583c8d81b1")},{$set:{"delayed":false}})

If you would like to replace the document you should use replaceOne

This command was added in mongodb 3.2 to avoid accidentality replacing the entire document when you mean to update a field
