Angular 2+ and Laravel - Internal Server Error - laravel

Question

For post request from Angular to Laravel I am getting error(Internal Server Error). But it successfully works in Postman.
api.php
<?php
use Illuminate\Http\Request;
Route::post('/addHouse', [
'uses' => 'HouseController#postHouse'
]);
HouseController.php
public function postHouse(Request $request)
{
$house=new House();
$house->houseName=$request->input('houseName');
$house->type=$request->input('type');
$house->for=$request->input('for');
$house->address=$request->input('address');
$house->price=$request->input('price');
$house->description=$request->input('description');
$house->bedrooms=$request->input('bedrooms');
$house->bathrooms=$request->input('bathrooms');
$house->area=$request->input('area');
$house->save();
return response()->json([
'house'=>$house
],201);
}
Cors.php(Middleware)
public function handle($request, Closure $next)
{
return $next($request)
->header('Access-Control-Allow-Origin','*')
->header('Access-Control-Allow-Methods','Get, POST, PUT, PATCH, DELETE, OPTIONS')
->header('Access-Control-Allow-Headers', 'Content-type, Authorization');
}
In Angular house.service.ts
addHouse(content) {
console.log(content);
const body = JSON.stringify({
content: content
});
const headers = new Headers({
'Content-Type':'application/json'
});
return this._http.post('http://localhost:8000/api/addHouse', body, {
headers: headers
});
}
My error -> POST http://localhost:8000/api/addHouse 500 (Internal Server Error)

I solved it by changing addHouse function. Thanks everyone..
addHouse(data) {
var headers = new Headers();
headers.append (
'Content-type','application/json'
);
return this._http.post('http://localhost:8000/api/addHouse', JSON.stringify(data), {
headers:headers
}).map(res => res.json());
}
