Mongo query using value that was serialized

I'm creating a child process to which I'm sending a serialized request. Request is parsed inside child process and some of its fields are needed to do mongo operations, but queries are not retrieving any values. Queries work fine with same values from unserialized request.Didn't help, but tried using:req.facilityId = mongoose.Types.ObjectId(req.facilityId), // loader.js const cp = require('child_process') exports.addExcel = async(req, res, next) => { req.objects.userId = req.objects.session.userId; req.objects.facilityId = req.params.facilityId; req.objects.file = req.file; const serializedObj = JSON.stringify(req.objects) try { let worker = cp.fork('./utils/excelHelper.js'); worker.send(serializedObj) } catch (error) { console.error(error) } } // childProcess.js const mongoose = require('mongoose'); const Facility = require('../models/facility'); (async () =>{ try { process.on('message', async function(serializedObj) { console.log('Object received in ExcelHelper:'); let req = JSON.parse(serializedObj); req.facilityId = mongoose.Types.ObjectId(req.facilityId), // findOne not working here, but working // if value was never serialized: let facility = await Facility.findOne({_id: req.facilityId}); doSomething(facility); }); } catch (e) { console.log(e); } })()
