executeAsync returns message: asynchronous script timeout

[rhazes]

Hello, 

I am wondering if there is any insight into the error message I receive back from the executeAsync function.

My code is below:

exports.command = function(selector, time,  cb) {
  var data = [{selector: selector, time: time}];


  function listenForCanvasRender(data, done) {
    var canvasElement = document.querySelector(data.selector);


    canvasElement.addEventListener('sdk.render', _.debounce(function(event) {
       done(true);
    }, data.time));
  }


  function handleResult(result) {
    var ret = result.value;
    if (cb) {
      cb(ret);
    }
  }

  this.executeAsync(listenForCanvasRender, data, handleResult)
};

The result value that is passed back is this:

'asynchronous script timeout: result was not received in 0 seconds\n  (Session info: chrome=50.0.2661.102)\n  (Driver info: chromedriver=2.9.248307,platform=Mac OS X 10.10.3 x86_64) (WARNING: The server did not provide any stacktrace information)\nCommand duration or timeout: 242 milliseconds\nBuild info: version: \'2.46.0\', revision: \'87c69e2\', time: \'2015-06-04 16:16:47\'

Any help is appreciated.

Many Thanks,

Rachel

You can try increasing the timeout with this command:
http://nightwatchjs.org/api#timeoutsAsyncScript. I see you are using a
pretty old selenium server version, you should consider upgrading it -
latest is 2.53 at this point. If you are only using Chrome then you
could use it directly as detailed here:
https://github.com/nightwatchjs/nightwatch/issues/948 (docs will be
updated soon).

Those are some nice tips. Thanks!

For the timeoutAsyncScript, do you recommend that I set that at the beginning of a session, perhaps globally in the beforeEach?

I'm definitely going to look into using WebDriver directly.
