MongoDB - Error with Postman - Data sending fails - node.js

Question

I have used Mean Stack to build a project. I have created a Report Form in which data can be inserted.
When I insert the data from the form the data is inserted to the collection.
But when I use Postman to insert data the data insertion fails.
Here are the code segments:
1.Front End Form - report.component.html
<form (ngSubmit)="savereportdata()" novalidate>
<ba-card>
<div class="form-group">
<label for="middleItemId">Item ID</label>
<input type="text" class="form-control" placeholder="Enter Item ID" [(ngModel)]="itemId" name="itemId">
</div>
<div class="form-group">
<label for="middleItemName">Item Name</label>
<input type="text" class="form-control" placeholder="Enter Item Name" [(ngModel)]="itemName" name="itemName">
</div>
<div class="form-group">
<label for="warrentyUntil">Warrenty Until</label>
<input type="date" readonly="" class="form-control">
</div>
<div class="form-group">
<label for="reportDescription">Description</label>
<textarea class="form-control" rows="3" [(ngModel)]="reportDescription" name="reportDescription"></textarea>
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</ba-card>
</form>
2.report.component.ts
import { NgModule,Component,Pipe,OnInit } from '#angular/core';
import { ReportItemService } from '../../../services/report-item.service'
#Component({
selector: 'app-report',
templateUrl: './report.component.html'
})
export class ReportComponent implements OnInit {
itemId:Number;
itemName:String;
reportDescription:String;
constructor(public reportservice:ReportItemService) {}
ngOnInit() {}
savereportdata() {
const reportitem = {
itemId:this.itemId,
itemName:this.itemName,
reportDescription:this.reportDescription
};
this.reportservice.reportitemdata(reportitem).subscribe(res=> {
console.log(res);
});
}
}
3.report-item.service.ts
import { Injectable } from '#angular/core';
import { Http,Headers} from '#angular/http';
import 'rxjs/add/operator/map';
#Injectable()
export class ReportItemService {
reportitem:any;
constructor(private http:Http) {}
reportitemdata(reportitem) {
let headers=new Headers();
headers.append('Content-Type','application/json');
return this.http.post("http://localhost:3000/reportItem",reportitem,{headers:headers}).map(res=>res.json());
}
}
4.Backend Model - report.js
const mongoose = require('mongoose');
const schema = mongoose.Schema;
const reportSchema = new schema({
itemId: { type: Number, required: true },
itemName: { type: String },
reportDescription: { type: String },
date: { type: Date }
});
module.exports = mongoose.model("ReportItem", reportSchema);
module.exports.saveReportItem = function(newreport, callback) {
console.log(newreport);
newreport.save(callback);
};
5.router - reportItem.js
const express = require('express');
const router = express.Router();
const config = require('../config/database');
const ReportItem = require('../models/request-report/report');
router.post("", function(req, res) {
const newreport = new ReportItem({
itemId: req.body.itemId,
itemName: req.body.itemName,
reportDescription: req.body.reportDescription,
date: new Date
});
ReportItem.saveReportItem(newreport, function(err, report) {
if (err) {
res.json({ state: false, msg: "data not inserted" });
}
if (report) {
res.json({ state: true, msg: "data inserted" });
}
});
});
module.exports = router;

I've been trying to figure out this problem for weeks but couldn't.
Thanks loads in advance!

You could try using the bodyParser module in the js code to grab the data from the request. I’ve had issues with this in the past.
