CastError : try implement a route and right away get error

i do a project in nodejs with express and mongo
now i tried do implement a simple route but i get an error
//this is the route
router.patch('/resetPassword/:token', authController.resetPassword)
//this is the resetPassword function
exports.resetPassword = (req, res, next) => {
console.log("work")
}
But as soon as I click on the request I get the error even the consul.log is not read

This is how you do it.
route.js
const router = require("express").Router();
const adminCtrl = require("./adminCtrl");
router.post("/login", adminCtrl.adminLogin);
adminCtrl.js
exports.adminLogin = (req, res,next) => {
}

Not returning the array objects from database Mongodb?

This is the code from server side i have created but says :
[
'60c65094d9e1242a18cf84da',
'60c650d7d9e1242a18cf84db',

app.post('/productsByKeys',(req,res)=> {

const productKeys = req.body;
productCollection.find({_id: {$in :ObjectID(productKeys)}})
.toArray((err,items)=> {
res.send(items);
console.log(" found by ids: ",documents)
console.log("RESPONSE :",err)
})
})

Instead of converting you array into ObjectId(), convert individual items inside the array into ObjectIds.
const productKeys = req.body;
let convertedKeys = productKeys.map((x) => ObjectID(x));
productCollection.find({_id: {$in :convertedKeys}})

Including subschemas in schemas doesn't seem to work for mongoose

This is how I defined my subschema and schema
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const JobSchema = new Schema ({
jobname: String,
jobstatus: String
})
const DataSchema = new Schema ({
username: {
type: String,
required: true,
unique: true
},
jobs: [JobSchema]
});
module.exports = mongoose.model("data", DataSchema);
This block of code is to utilize the schema above as a model
const express = require("express");
const router = express.Router();
const Data = require("../../models/Data");
router.post("/", (req, res) => {
const newData = new Data({
username: req.body.username,
jobs: req.body.jobs
});
newData
.save()
.then(data => res.json(data))
.catch(err => console.log(err));
});
module.exports = router;
Data I attempted to put in:
{
username: France,
jobs: [{jobname: Google, jobstatus: applied}]
}
Error:

I have read from several sources on the internet that the idea of subschemas(a.k.a subdocuments) is possible. However, when I try to implement it as shown above, it fails to work. What is the reason behind this?

The error looks like you are assigning a string to jobs instead of the array object. I think what you are currently saving is
{
username: "France",
jobs: "[{jobname: Google, jobstatus: applied}]" // the whole array as string
}
What you should be saving is
{
username: "France",
jobs: [{jobname: "Google", jobstatus: "applied"}]
}
Please console log the req.body.jobs and check if its a proper JSON array

You can't use schema in another schema by storing it in a "jobs".
You can give a reference to "jobschema" as below.
jobs : [{
type: Schema.ObjectId,
ref: 'JobSchema'
}]

and here is mylist.js file:
var jwt = require('jwt-simple');
module.exports = function (req, res) {
var token = req.headers.authorization.split(' ')[1];
var payload = jwt.decode(token, "shhh..");
if(!payload.sub) {
res.status(401).send({
message: 'Authentication failed'
});
}
if(!req.headers.authorization){
return res.status(401).send({
message: 'You are not authorized'
});
}
res.json(mylist);
};
var mylist = [
'Proj 1',
'Proj 2',
'Proj 3',
'Proj 4'
];
i am trying to see if the user is authorized to access the mylist resource on frontend.
does anyone have any idea?

you assume it's a string, even if you don't know if there really is a string there.
You should add some error checking first
module.exports = function (req, res) {
if (typeof req.headers.authorization !== 'string') {
res.sendStatus(400);
return;
}
var tokens = req.headers.authorization.split(' ');
if (tokens.length < 2) {
res.sendStatus(400);
return;
}
var token = tokens[1];
var payload = jwt.decode(token, "shhh..");
if(!payload.sub) {
res.status(401).send({
message: 'Authentication failed'
});
}
...
};
Edit: But why exactly do you want the second token and not the first?

NodeJs, AngularJs, Mongoose giving error: TypeError: Object.keys called on non-object at Function.keys (native)

Heres my code relative to the problem:
server.js file:
app.post('/user', function(req,res){
console.log(req.body);
var user = mongoose.Schema('User',req.body);
user.save(function(err,user){
if(err) console.log(err);
console.log("Successfully added user to MongoDB");
});
res.sendStatus(200);
});
Angular Controller:
app.controller('RegisterController',['$scope','$http',function($scope,$http){
$scope.submitData = function(user){
var dob = user.dob.day.toString()+"/"+user.dob.month.toString()+"/"+user.dob.year.toString();
user.dob = dob;
var post = $http.post('/user', user);
post.success(function(data,status,headers,config){
console.log(data);
console.log(status);
console.log('Success!');
});
}
$scope.countTo= function(count){
var array = [];
for(i = 1; i<=count; i++){
array.push(i);
}
return array;
}
$scope.countFrom = function(startingPoint,count){
var numbers = [];
for(i=startingPoint; i>startingPoint-count;i--){
numbers.push(i);
}
return numbers;
}
}

The error occurs when I click the send button on the website... Any help please?

It looks like you are doing the Mongoose side of things a little wrong here. Not 100% sure this is the cause of your error, but it's still problematic.
var user = mongoose.Schema('User',req.body);
This isn't doing what you think it does. Schema expects an object representing the Schema as the first argument e.g., {email:String, dob:String}. Passing the string 'User' here would not work.
Instead, you want to reference the model you've already defined. You can do so by either
exporting and subsequently including your user model as a module like var User = require('UserModel.js')
or directly referencing the model from Mongoose (assuming it's defined in the app before you call it) like var User = mongoose.model('User);
Once you have a reference to the Model object you can initialize a new document. In your case you probably want your code to read something like
var user = new User(req.body);
user.save(function(err,user){...}
Try that and then let us know if you are still seeing that error.
