Reindex issue using OpenSearch

[ganeddact]

Preconditions

Opensearch 2.12

Magento Version : 2.4.7-p4

ElasticSuite Version : 2.11.10

Environment : developer

Steps to reproduce

1. Run bin/magento indexer:reindex

Expected result

1. All indexes complete normally

Actual result

1. Catalog Search and ElasticSuite Category Indexing indexes return an error:
   Catalog Search index process error during indexation process:
   OpenSearch\Client::performRequest(): Return value must be of type array|string|null, GuzzleHttp\Ring\Future\FutureArray returned
   ElasticSuite Category Indexing index process error during indexation process:
   OpenSearch\Client::performRequest(): Return value must be of type array|string|null, GuzzleHttp\Ring\Future\FutureArray returned

With 2.4.7-p3 I didn't notice this problem, so I'm wondering if the security patch p9 has introduced something that broke this, or if it's something else.

I had the same before few days. You are probably using opensearch-php >= 2.4.0 which are comes with update of magento 2.4.7-p4.

My suggestion is to downgrade opensearch-project/opensearch-php to version 2.3.1 and update elasticsuite to latest version 2.11.10.1

For reference: #3522 and https://github.com/Smile-SA/elasticsuite/releases/tag/2.11.10.1

I was not go in depth, because i just was to fix it on the production environment.

Thanks for your help, I didn't notice that topic before.
I've moved to the latest version and downgraded opensearch-php to 2.3.1 and the problem has disappeared.
Thanks again
