Cannot xor mongodb field from nodejs without mongoose - node.js

Question

I'm trying to xor the field status, in a document such as this:
{
"_id" : ObjectId("58c51e1aedb6e4000410ddbf"),
"query" : "developer",
"user_id" : "1413322622039651",
"status" : 1,
"links" : [
"840673302343483394",
"840672745222483968",
"840672580717686785",
"840672427550089216",
"840582170548850688",
"840581988918669312"
],
"links_size" : 6,
"created" : ISODate("2017-03-12T10:08:26.369Z")
}
I'm using this code:
var args = {'_id': new ObjectID(queryId)};
var bit = {$bit: {'status': {xor: 1}}};
db.collection('query').update(args, bit, function(err, result) {});
The query produces no error but the field status is not changed. I think that the problem is that it interprets 1 as a double not as a integer. I tried: parseInt(1) but it also had no effect. I tried to use NumberInt(1) but got the error NumberInt is not defined.
So I can't make it work in my code; however, the equivalent query through the mongo shell works as expected:
db.query.update(
{"_id":ObjectId("58c3b98e458f0700045b1846")},
{"$bit":{"status":{"xor":NumberInt(1)}}}
)
I googled and found that NumberInt is present in the mongoose-int32 package but it requires mongoose. I don't want to add mongoose as a dependency for my project so I'm looking for another solution.

The problem comes from the status field type stored in your document
here it is
{ "status" : 1, ... }
but you should have this:
{ "status" : NumberLong(1), ... }
First, convert all status field to NumberLong using this code (run it directly in the shell)
db.query.find().forEach( function(obj) {
obj.status = new NumberLong(obj.status);
db.query.save(obj);
});
then just update your previous code like this :
const MongoClient = require('mongodb').MongoClient
const ObjectId = require('mongodb').ObjectId
const Long = require('mongodb').Long
MongoClient.connect('mongodb://localhost:27017/database', function (err, db) {
if (err != null) {
console.log(err)
} else {
let args = {'_id': new ObjectId('58c64231b13b6239d9e496da')}
let bit = {$bit: {'status': {xor: Long.fromInt(1)}}}
db.collection('query').update(args, bit, function (err, result) {
if (err != null) {
console.error(err)
}
db.close()
})
}
})
This worked using:
node v7.3.0
npm package mongodb 2.2.24
MongoDB 3.4.1
