ElasticSearch update fails after deleting product attribute

[SoleneGK]

Expected behavior

Product is deleted in database
Elasticsearch index is updated
Product list is displayed

Current behavior

Product is deleted in database
Elasticsearch index is not updated
A 500 error occurs

Steps to reproduce

1. Create a product
2. Delete the product

Detailed description

The error happens because BitBag\SyliusElasticsearchPlugin\EventListener\ResourceIndexListener is called on the event sylius.product.post_delete. Since the product removal has been processed by Doctrine, the product object id has been set to null.

Listener config file : src/Resources/config/services/event_listener.xml

This problem also happen when deleting a product attribute, an option or a product variant.

Thank you for the fix, it works for deleting products, but not for deleting product variants. Indeed, I still get this error when I try to delete a variant:
