Express - passing 2 empty array not working

Question

This is strange. I am passing 2 empty arrays in my payload and the post call is failing.If I pass only 1 empty array, then the call is successful.

I am using Express: ^4.13.0.

Angular Code :

$scope.login = function(){        
  var temp = {};
  temp.username = $scope.username;
  temp.password = $scope.password;
  temp.speed=[]; // <---- code works without this line
  temp.notification=[];

  loginService.login(temp).then(function(data){
    $state.transitionTo('root.dashboard');
  }, function(error) {               
    console.log("error" , error);
    $scope.message = error.data.message;
  });
}

Node Route :

app.post('/connect/local', User.login);

I am using passport for login strategy.

In the server, I get this error

Error: Can't set headers after they are sent.

Any clue will help.

Hi Karthik, Can you show your code for the post call on the angular side and the post route on the express side? — R.A. Lucas, Oct 19 '16 at 18:23
Also your code looks like it is in angular, and not express. In addition, your code works as expected. — tcooc, Oct 19 '16 at 18:25
You can probably refer to this answer: http://stackoverflow.com/questions/7042340/node-js-error-cant-set-headers-after-they-are-sent I suspect you're not calling `return` on the error in `User.login` on the server side — R.A. Lucas, Oct 19 '16 at 18:29
@ralucas if I pass one empty array ,the post call is successful .If I pass more than one ,then the call fails. — Karthik Renkarajan, Oct 19 '16 at 18:33
