Data insert instead of update after EntityManager Reset when closed

[bilal-renegade]

I have a problem with entityManager when flushing multiple entities,
try {
$products = $this->getProducts();
$this->processUpdateProducts($products);
} catch (EntityManagerClosed $e) {
$this->managerRegistry->resetManager();
$this->entityManager = $this->managerRegistry->getManager();
$products = $this->getProducts();
$this->processUpdateProducts($products);
}
I load more than 200 products and have a batch flush max of 50 at once. in some scenarios entityManager is closed, I load again those products that are not executing and then update products,
then it throw ORMInvalidArgumentException (Multiple non-persistance entities) because of in unitOfWork method doPersist and line no 2054
$entityState = $this->getEntityState($entity, self::STATE_NEW);
is always return 2 which is incorrect I want to update not insert,
