angularjs - $http not passing on .success -

i have function uses textract (https://www.npmjs.com/package/textract).

$scope.textract = function(fileurl) {         var req = {         method: 'get',         url: 'http://localhost:3000/textract',         params: {             fileurl: fileurl         }     };      $http(req)         .success(function(status, data) {             console.log('status is: ' + status);             console.log('data is: ' + data);         })         .error(function(status, response) {             console.log('error status is: ' + status);             console.log('error response is' + response);         }); }; 

on express server, have:

function countwords(text) {     var s = text ? text.split(/\s+/) : 0; // splits text on space/tab/enter     return s ? s.length : ''; }  app.get('/textract', function(req, res, next) {      filepath = path + req.query.fileurl;      textract(filepath, function(error, text) {         if (!error) {             console.log(text);             return res.status(200).send(countwords(text));         } else {             return res.sendstatus(400);         };     });  }); 

on server, console.log(text) , countwords(text) work.

question: on client, $http prints on .error, in other words, it's not passing on .success (which believe should do, because on server word counter working ok).

any ideas?
