Error passing JSON arguments

I am trying to make an insertion in Mongodb passing some arguments in JSON: 

{
    "name": "TESTE", 
    "category": "B", 
    "service": "Novo processo", 
    "description": "Novo Teste", 
    "active": false,
    "classmodels": [
        {"id": "5bbe37ef8eb26d0025624fcd", "amount": 10},
        {"id": "5bbe37ef8eb26d0025624fcd", "amount": 14}
    ]
}

Is returning the following error: 

Error: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters

It is also returning the status code as 500 (Internal Server Error), but I am managing to use other endpoints without any problem.

The functions in Nodejs that I’m using are these:

First to be called.

addStandardClassTemplate: function(req, res) {
        let name = req.body.name;
        let category = req.body.category;
        let service = req.body.service;
        let description = req.body.description;
        let active = req.body.active;
        let classmodels = req.body.classmodels;
        console.log('Entrou no método de Adicionar Template de Aula Padrão');
        classtemplatesMethods.add.addStandard(name, category, service, description, active, classmodels)
            .then((result) => {
                res.status(200).send(result);
            })
            .catch((error) => {
                res.status(404).send(error);
            });
    },

Second call.

addStandard: function(name, category, service, description, active, classmodels) {
        classmodels.forEach((item, index) => classmodels[index] = ObjectId(item));

        let NewValues = {
            name: name,
            category: category,
            service: service,
            description: description,
            active: active,
            classmodels: classmodels,
        };
        console.log('QUERY Adicionar Template de Aula Padrão');
        return new Promise((resolve, reject) => {
            mongoMethods.add.insert(targetcollection, NewValues)
                .then((result) => resolve(result))
                .catch((error) => reject(error));
        });
    },

  • Hello Henrique, I saw that in your model you have this line: classmodels.foreach((item, index) => classmodels[index] = Objectid(item)); it is really necessary to re-populate the classmodels array with the same values?

  • I am using this foreach to transform the id I pass to Objectid. I couldn’t understand what you said about re-populating the array.

  • Note that in this classmodels[index] You are rewriting the entire record and not only the .id, same thing with the ObjectId(item), should be ObjectId(item.id)

Through the baseball bat that rolled in the comments of the question we detected that only one was missing .id =)

//classmodels.forEach((item, index) => classmodels[index] = ObjectId(item));
classmodels.forEach((item, index) => classmodels[index].id = ObjectId(item.id));

Henry, look at this Mongodb documentation on Objectid: official documentation link: Mongo DB documentation

var Db = require('mongodb').Db,
    MongoClient = require('mongodb').MongoClient,
    Server = require('mongodb').Server,
    ReplSetServers = require('mongodb').ReplSetServers,
    ObjectID = require('mongodb').ObjectID,
    Binary = require('mongodb').Binary,
    GridStore = require('mongodb').GridStore,
    Grid = require('mongodb').Grid,
    Code = require('mongodb').Code,
    BSON = require('mongodb').pure().BSON,
    assert = require('assert');

// Create a new ObjectID
var objectId = new ObjectID();
// Convert the object id to a hex string
var originalHex = objectId.toHexString();
// Create a new ObjectID using the createFromHexString function
var newObjectId = new ObjectID.createFromHexString(originalHex)
// Convert the new ObjectID back into a hex string using the toHexString function
var newHex = newObjectId.toHexString();
// Compare the two hex strings
assert.equal(originalHex, newHex);
