orm: Call to a member function resolveAssociationEntries() on boolean {"detail":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Call to a member function resolveAssociationEntries() on boolean at /www/vendor/doctrine/orm/lib/Doctrine/ORM/Cache/DefaultQueryCache.php:140)"}

The following mistakes occur occasionally，and I can’t find the solution

Call to a member function resolveAssociationEntries() on boolean {"detail":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Call to a member function resolveAssociationEntries() on boolean at /www/vendor/doctrine/orm/lib/Doctrine/ORM/Cache/DefaultQueryCache.php:140)"}

version: doctrine/orm V2.6.0 in DefaultQueryCache.php at line 140

        $entries   = $region->getMultiple($cacheKeys);
        // @TODO - move to cache hydration component
        foreach ($cacheEntry->result as $index => $entry) {
            $entityEntry = is_array($entries) && array_key_exists($index, $entries) ? $entries[$index] : null;

            if ($entityEntry === null) {
                if ($this->cacheLogger !== null) {
                    $this->cacheLogger->entityCacheMiss($regionName, $cacheKeys->identifiers[$index]);
                }

                return null;
            }

I think the parameter $entityEntry sometimes will be false , then occur the mistakes.

change if ($entityEntry === null) to if ($entityEntry === null || $entityEntry === false ) . Is this a good solution ?

I need your help. Thank you very much.
