It seems like you code against a specific sub-type and not the parent class Exception as the method getStatusCode() does only exist in the following sub-classes of Exception: League\Route\Http\Exception, League\Route\Http\Exception\BadRequestException, League\Route\Http\Exception\ConflictException, League\Route\Http\Exception\ExpectationFailedException, League\Route\Http\Exception\ForbiddenException, League\Route\Http\Exception\GoneException, League\Route\Http\Exception\ImATeapotException, League\Route\Http\Exception\LengthRequiredException, League\Route\Http\Exception\MethodNotAllowedException, League\Route\Http\Exception\NotAcceptableException, League\Route\Http\Exception\NotFoundException, League\Route\Http\Exception\PreconditionFailedException, League\Route\Http\Exception\PreconditionRequiredException, League\Route\Http\Exception\TooManyRequestsException, League\Route\Http\Exception\UnauthorizedException, League\Route\Http\Exception\UnprocessableEntityException, League\Route\Http\Exception\UnsupportedMediaException, Symfony\Component\HttpKernel\Exception\AccessDeniedHttpException, Symfony\Component\HttpKernel\Exception\BadRequestHttpException, Symfony\Component\HttpKernel\Exception\ConflictHttpException, Symfony\Component\HttpKernel\Exception\GoneHttpException, Symfony\Component\HttpKernel\Exception\HttpException, Symfony\Component\HttpKernel\Exception\LengthRequiredHttpException, Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException, Symfony\Component\HttpKernel\Exception\NotAcceptableHttpException, Symfony\Component\HttpKernel\Exception\NotFoundHttpException, Symfony\Component\HttpKernel\Exception\PreconditionFailedHttpException, Symfony\Component\HttpKernel\Exception\PreconditionRequiredHttpException, Symfony\Component\HttpKernel\Exception\ServiceUnavailableHttpException, Symfony\Component\HttpKernel\Exception\TooManyRequestsHttpException, Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException, Symfony\Component\HttpKernel\Exception\UnprocessableEntityHttpException, Symfony\Component\HttpKernel\Exception\UnsupportedMediaTypeHttpException.
