Angular JS Node JS Bad request error post - angularjs

Question

I am using angularjs with node js as server.
I am passing data this way from UI.
schatApp.controller('registerController', function($scope,$location,$http) {
$scope.RegisterCredentials=function(){
var data={
"firstName":"simhachalamrsdafrds",
"lastName":"ajay",
"username":"asfsd",
"email":"ajayfds14#m.com",
"provider":"local",
"displayName":"amruth"
}
// var json = "{\"firstName\": \"firstName\",\"lastName\": \"lastName\",\"username\": \"username\",\"email\": \"email\"}";
var config = {
headers : {
contentType:'application/json; charset=utf-8',
dataType: 'json'
}
}
$http.post("/register",JSON.stringify(data),config).then(function sucess(result){
// alert(JSON.stringify(result));
},function failure(result){
// alert(JSON.stringify(result));
});
}
});
This is my backend code
app.post('/register',function(req,res){
var data={
firstName:'simhachalam',
lastName:'ajay',
username:'asfsdq',
email:'ajayfds14#mq.com',
provider:'local',
displayName:'amruth'
}
console.log("111...............");
//console.log(req.body);
//res.setHeader('Content-Type', 'application/json');
core.account.create('local',data,function(err){
if (err) {
var message = 'Sorry, we could not process your request';
if (err.code === 11000) {
message = 'Email has already been taken';
}
return res.status(400).json({
status: 'error',
message: message
});
}
res.status(201).json({
status: 'success',
message: 'You\'ve been registered, ' +
'please try logging in now!'
});
});
});
I am getting 400 bad request.

Its very difficult to say what could be the issue, you need to do a console.log(err) object. can you give that information for us here.
if (err) {
var message = 'Sorry, we could not process your request';
if (err.code === 11000) {
message = 'Email has already been taken';
}
return res.status(400).json({
status: 'error',
message: message
});
}
The above code clearly states that you are returning res.status(400), can you change your $http.post to below and check.
$http({
method: 'POST',
url: "/register",
data: JSON.stringify(data),
headers: {'Content-Type': 'application/json; charset=utf-8'}
});
hopefully your /register endpoint is hosted on the same server where you are serving the client from.
