ReflectionException on a property that does not exist

[MichaelBelgium]

We have a local environment where everything works perfectly, on our production env we get this error from an entity:

Is this cache related? On the production env we do use apcu cache

[MichaelBelgium]

So a quick fix is doing apcu_clear_cache on every http request, which is unacceptable...

[derrabus]

Can you provide a minimal application or a test case that reproduces this issue? If so, please open an issue on our bug tracker.

[MichaelBelgium]

Yeah, i can't even reproduce it locally. Even when using the apcuadapter locally, otherwise it's always been the arrayadapter as cache.

More info:

• the property $text has actually been moved from that entity
• another quick fix is not setting the metadatacache in ORM\Configuration class
• executing service php7.4-fpm reload fixes it too but only for 2-3 minutes?

$cache = new ApcuAdapter();

$emConfig = new Configuration();
        $emConfig->setProxyDir(APP_BASE_PATH . '/var/cache/doctrine');
        $emConfig->setProxyNamespace('DoctrineProxies');
        $emConfig->setAutoGenerateProxyClasses(false);
        $emConfig->setMetadataDriverImpl($driverChain);
        //fixes it on production
        //$emConfig->setMetadataCache($cache);
        $emConfig->setQueryCache($cache);
        $emConfig->setResultCache($cache);

Also found this symfony/symfony#24545, it's the same error but that fix is not applicable for me as I'm using a custom framework, not symfony

[derrabus]

Without a reproducer, I'm having a hard time to tell if there's anything we could fix on the ORM's side.

[MichaelBelgium]

I think i know the issue, but i'd need a confirmation.

On the production environment we have 2 branches with different entities and possibly metadata and both use apcu cache.
So 2 branches with removed/edited/added properties and 1 apcu cache.

If i clear the apcu cache and go to one branch => there's a refection error in the other branch - and vice-versa

If this is the cause, i suppose we need to change cache adapters or add a namespace in the ApcuAdapter ?

[derrabus]

Yes. Two applications writing into the same cache sounds like asking for trouble.
