Hi,

I am getting the error NameError: name ‘writeConcern’ is not defined while running user_preferences test.

Could you please help me understand the issue?

Here is the error script:

    """
    Ticket: Durable Writes

    Please increase the durability of this method by using a non-default write
    concern with ``insert_one``.
    """

    try:
        # TODO: User Management
        # Insert a user with the "name", "email", and "password" fields.
        # TODO: Durable Writes
        # Use a more durable Write Concern for this operation.

      db.users.insert_one({"name": name, "email": email, "password": hashedpw}, {writeConcern: {w: "majority"}})

E NameError: name ‘writeConcern’ is not defined
