$result = Json::encode($result);

Internal Server Error means that your code has fatal errors and error displaying is turned off. If you want to see the error itself, you must enable error displaying.
Check out the following question with its answers: How do I get PHP errors to display?
After you see the error, you can fix it.
PS:
$testGrid_name = $_GET['testGrid_name'];
This is not a recommended way to access GET variables. Use Yii::$app->request->get('testGrid_name') instead
