I updated mongoose to latest version and this error occurs. In this example new user is being created and his data is to be added to an existing user. the user is created but no longer adds his information to the second. The first time a function was called, it was added and no more.

My code:

const member_reg_post = async (req, res) => {
    var { parentID, login, password, fname, surname, age=null } = req.body;

    try {
        const isAdult = false;
        const user = await User.create({ login, password, fname, surname, isAdult });
        const member = await {
            _id: user._id,
            fname: user.fname
        };
        console.log(member);
        const memberAdd = await User.updateOne(
            { _id: parentID },
            { $addToSet: { familyMembers: member }},
            (err) => {
                if (err) {
                    console.log(err);
                    res.status(400).json({ operationStatus: 'Failed'});
                } else {
                    res.status(201).json({ operationStatus: 'Completed'});
                }
            }
        );

        console.log('member_reg_post -> job done');
        res.status(200).json(user);
    } catch (err) {
        console.log(err);
    }
};

Error:
