Can't catch AuthorizationException in Laravel Handler

in Handler head:

use Illuminate\Auth\Access\AuthorizationException;

in handler render method:

    if ($e instanceof AuthorizationException) {
        return response()->json(['message' => $e->getMessage()], 403);
    }

form request:

use Illuminate\Auth\Access\AuthorizationException;

class SomeFormRequest extends Request
{
    public function authorize()
    {
        $this->error = 'some text';
        return false;
    }

    protected function failedAuthorization()
    {
        throw new AuthorizationException($this->error);
    }
}

and part of my output (it's error 500):

{
    "message": {
    "xdebug_message": "<tr><th align='left' bgcolor='#f57900' colspan=\"5\"><span style='background-color: #cc0000; color: #fce94f; font-size: x-large;'>( ! )</span> Illuminate\\Auth\\Access\\AuthorizationException: some text

Maybe you have some solution?
