I'm getting a ParseError even though my JSON validates on jsonlint.com.

Here is the jQuery code:

```
$.ajax({
    url: path,
    type: 'GET',
    data: {},
    cache: false,
    dataType: 'json',
    contentType: 'application/json; charset=utf-8',                  
    success: function (data) {
        var a = 'breakpoint here doesn't activate';
    },
    error: function (x, y, z) {
        var b = 'code execution stops at a breakpoint here.';
    }
});

```

Here is the PHP code that is being called:

```
function getAllAnswersToHitViaAjax($theJobName) {
    $testData[0] = 'testing123';
    $encodedData = json_encode($testData);
    echo $encodedData;
    return;
}

```

This comes back to a breakpoint set in the error: function of my .ajax call. Parameter Y is set to "parseerror", and x.responseText = 

```
["testing123"] 

```

I've been looking into this for hours so far. I've looked at many relevant StackOverflow posts, but none have solutions that work in this case.

How can I get a success response from this .ajax call?

Thanks very much in advance to all for any info.
