contentResource.getChildren($routeParams.id), without options paramer results in error, this wasn't the case in 7.1.4

Failed to retrieve children for content item 1317

Attempted to divide by zero.

If I add options as a second parameter to the call the error is gone

     $scope.options = {
         pageSize: 10,
         pageNumber: 1,
         filter: '',
         orderBy: 'SortOrder',
         orderDirection: "asc"
     };
