Javascript 如何在mongodb中将$push、$set和$inc组合在一起？

基本上，我在mongodb中使用环回，希望推送数据，设置数据并将数据相加，得到最终结果

为此我试过这个

db.invoice.findOneAndUpdate({ _id: ObjectId(req.params.id) },
        {
            $push: { payment: paymentData }
            , $set: { payment_status: true, updated_at: new Date() }
            , $inc: { total_amount_paid: paidAmt }
        }
        ,
        function (err, doc) {
            if (err) { return new Error(err); }
            else {
                if (doc.result.n>0) {
                    setTimeout(function () { }, 200);
                    console.log(" Invoice updated with Payment info.");
                    nextCall(null, { code: 200, data: doc.result });
                } else {
                    console.log("Something went wrong while payment info updation.")
                    nextCall(null, { code: 400, status: 'Something went wrong while payment info updation.' })
                }
            }
        });
    });

}

如果我删除回调函数 它正在推送、设置值并增加支付的总金额。$inc

如果我想实现案例2，有人能告诉我哪里做错了吗

谢谢

一起执行

$push，$inc

操作

查找查询：

db.getCollection('noti').find({})

结果：
