Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if \Psr\Http\Server\MiddlewareInterface::class can be an interface. If so, you could instead use ReflectionClass::implementsInterface.

            return new $middleware;
        }
        if (is_callable($middleware)) {
            return new CallableMiddlewareDecorator($middleware);
        }
        throw new \InvalidArgumentException('Invalid middleware format');
    }
