Not found jwt token exception translate

[furkandura]

Why jwt not found exception cannot be translated while other exception messages can be translated ?

$exception = new MissingTokenException('JWT Token not found', 0, $authException);
        $event = new JWTNotFoundEvent($exception, new JWTAuthenticationFailureResponse($exception->getMessageKey()), $request);

        $this->eventDispatcher->dispatch($event, Events::JWT_NOT_FOUND);
