I had an error during an ajax request, and while ezplatform was trying to handle error in EzSystems\PlatformUIBundle\Controller\ExceptionController at L18, code returns @Twig/Exception/exception_full.html.twig string value in $template variable.

Now as you can see on L25, code is trying to clone the value in $template variable, which is failing with following error because its a string and not an object.

    FatalErrorException in ExceptionController.php line 25:
    Error: __clone method called on non-object

Is this a problem in my application side or this is problem in ExceptionController?
