Pass the token of an AngularJs controller to a Laravel API

I am trying to pass the token that I have in my controller to authenticate to an API in Laravel. But I'm encountering the error:

  

"token_not_provided"

Note: I am using JWTAuth with Laravel 5.4

Follow my API:

use Illuminate\Support\Facades\Validator;
use Illuminate\Http\Request;
use App\User;
use Illuminate\Support\Facades\DB;
use App\Http\Requests\PessoaRequest;
use Tymon\JWTAuth\Exceptions\JWTException;
use Tymon\JWTAuth\Facades\JWTAuth;

class PessoaController extends Controller
{

protected $user;

    public function __construct(\Illuminate\Http\Request $request)
{
    $header = $request->header('Authorization');

    return response([
        'status' => 'success'
    ]) ->header('Authorization', $header);
}

Angular Controller:

(function() {
 app.controller('MemberController', [
'$scope', '$rootScope', 'AppConfig', '$http',
function($scope, $rootScope, AppConfig, $http) {
  var vm = this;
  $rootScope.page.title = 'SEC BASE';

  $rootScope.authenticated = true;
  $scope.token = $rootScope.user.remember_token;
   getMembers();

    // Obtem a listagem de todos os usuarios
  function getMembers() {
    $scope.token = $rootScope.user.remember_token;
    Loading.show();
    $http({
      method: 'GET',
      url: AppConfig.ApiUrl + 'members',
   headers: {
            'Content-Type' : 'application/x-www-form-urlencoded; charset=UTF-8',
            'Accept': 'application/json',
            'Authorization ' : 'Bearer' + $scope.token,
      }
    }).then( response => {
      // console.log(response);
      $scope.members = response.data;
    }).finally(Loading.hide)
      .catch(function(err) {
            console.log(err);
        });
  }
  ]);
})();

Handler.php:

use Exception;
use Illuminate\Auth\Access\AuthorizationException;
use Illuminate\Auth\AuthenticationException;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Tymon\JWTAuth\Facades\JWTAuth;
public function render($request, Exception $exception)
{
    // detect instance
    try {
        $user = JWTAuth::parseToken()->authenticate();
    } catch (Exception $e) {
        if ($e instanceof \Tymon\JWTAuth\Exceptions\TokenInvalidException){
            return $this->respondWithError("Token is Invalid");
        }else if ($e instanceof \Tymon\JWTAuth\Exceptions\TokenExpiredException){
            return $this->respondWithError(['error'=>'Token is Expired']);
        }else{
            return $this->respondWithError(['error'=>'Something is wrong']);
        }
    }
    return $next($request);
}
