Error in using sdk in Symfony with caching

[SweetSallyBe]

When I get a model from the graph, I get the correct model. But I'm using caching in Symfony to save requests.

return $this->cache->get($cacheKey, function (ItemInterface $item) use ($type, $email) {
            $item->expiresAfter(self::CACHE_EXPIRES_IN_SECONDS_SHORT);
        try {
            $requestConfig
                = new GroupsRequestBuilderGetRequestConfiguration(queryParameters: GroupsRequestBuilderGetRequestConfiguration::createQueryParameters(filter: 'startsWith(mail,\''
                . $email . '\')'));

            $groups = $this->graphClient->groups()->get($requestConfig)->wait()->getValue();
            if ($groups) {
                foreach ($groups as $group) {
                    if ($group instanceof \Microsoft\Graph\Generated\Models\Group && $group->getMail() == $email) {
                        return $group;
                    }
                }
            }

            return null;
        } catch (ApiException $exception) {
            $this->handleException($exception);
        }

        });

In my local machine, this gives no trouble, when testing this. On my remote machine, I get an error

In DefaultMarshaller.php line 50:
Serialization of 'Closure' is not allowed 

It seems the serialization does not work well on this model?

Any suggestions? Tim
