Getting error when deserializing JSON #30

@sridharbandi I am using your accessibility libray for accessibility testing of Salesforce UI , however the test is failing when after " axeRunner.execute();" Below is the code for executing the Axe scanning 

                axeRunner = new AxeRunner(getDriver());
                getDriver().get(<salesforceurl>);
                JavascriptExecutor javascriptExecutor = (JavascriptExecutor) getDriver();
                String axe = Reader.getInstance().getAXE();
                javascriptExecutor.executeScript(axe);
                axeRunner.execute();

Below is the error I am getting

Any help in resolving this error is appreciated.

The code works fine I run it against Google page (google.co.nz)

In the first "node" object, the "target" field is correctly represented as an ArrayList of Strings:

"target" : [ ".test-listViewManager" ] However, in the second "node" object, the "target" field is represented as a nested array, which is not expected:

"target" : [ [ "one-appnav", "one-app-nav-bar", ".navUL" ] ]

Fixed in this PR

@makrandv Can you please scan your website with AXE Extension and check is the results displayed correctly? For axeRunner the origin axe.min.js is used from axe-core, and nested array doesn't looks correct for me. Can you please include the scan result here? You can use next script

var script = document.createElement('script');
script.src = 'https://cdnjs.cloudflare.com/ajax/libs/axe-core/4.7.2/axe.min.js';
document.head.appendChild(script);

script.onload = function() {
  axe.run(function(err, results) {
    if (err) throw err;
    console.log(JSON.stringify(results, null, 2));
  });
};
