How do I catch error when creating a Mongodb ObjectId using node js

Question

var criteria = Mongoose.Types.ObjectId(payloadData.skillId) ,

when I pass incorrect Id following error message is occured.

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

Answer 1

The mongo _id is 12-byte BSON type ObjectId

var mongoose = require('mongoose');

var id = '1111adda111';
// var id = payloadData.skillId;

console.log(mongoose.Types.ObjectId.isValid(id)); // false
var cond = mongoose.Types.ObjectId.isValid(id)

if (cond) {
    // do the required operation
} else {
    console.log('not a valid id');
}

Answer 2

Passing incorrect Mongo _id to Mongoose.Types.ObjectId() constructor throws BSONTypeError which can be caught in a try catch block.

import { BSONTypeError } from 'bson';

try {
    const id = Mongoose.Types.ObjectId('xyz');
}
catch {
    if (e instanceof BSONTypeError) {
        console.log('id is invalid');
    }
    else console.log('some other error');
}
