Mongoose: RangeError: Maximum call stack size exceeded while updating data to the database after adding jsonwebtoken in url

[rohan-paul]

In my App (A messenger app, when I enter in the new message, in the message (string) input, and click on submit, the node server closes giving me the below error
Although the new message that I am submitting in the in the input form gets saved in the database. And when I restart the node server, it shows up.

/home/paul/codes/ng2/Seed-MEAN-Feb18-WIP/node_modules/mongodb/lib/utils.js:132
      throw err;
      ^

The content in my ../models/messages.js

var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var User = require('./user');

var schema = new Schema({
    content: {type: String, required: true},
    user: {type: Schema.Types.ObjectId, ref: 'User'}
});

schema.post('remove', function (message) {
    User.findById(message.user, function (err, user) {
        user.messages.pull(message);
        user.save();
    });
});

module.exports = mongoose.model('Message', schema);

This issue started happening after I inserted the code for jsonwebtoken in ./message/message.service.ts file for adding the token to my post url

addMessage(message: Message) {
        const body = JSON.stringify(message);
        const headers = new Headers({'Content-Type': 'application/json'});
        const token = localStorage.getItem('token')
            ? '?token=' + localStorage.getItem('token')
            : '';
        return this.http.post('http://localhost:3000/message' + token, body, {headers: headers})
            .map((response: Response) => {
                const result = response.json();
                const message = new Message(
                    result.obj.content,
                    result.obj.user.firstName,
                    result.obj._id,
                    result.obj.user._id);
                this.messages.push(message);
                return message;
            })
            .catch((error: Response) => Observable.throw(error.json()));
    }

Hi @rohan-paul,

thanks for making this easy to trouble shoot. I cloned your repo and there are 2 lines that need to be changed to make it work:

after making these changes* I was able to add messages without it crashing.
I don't have any meaningful experience with ts, and I got an error on npm install about native compiling some of the ts packages, so I just edited the js without digging into ts. hope this helps.
