Cannot use _delete_by_query in ESSingleNodeTestCase tests with 8.X version.

Elastic Stack Elasticsearch

Hi,
I'm just migrating my application from ES 7.17 to ES 8.8.2 and faced one issue.
I'm using ESSingleNodeTestCase to check my implementation.
My application uses Java API Client 8.8.
I figured out how to run HTTP inside tests and most of tests run correctly except all using _delete_by_query.

Details using 'co.elastic.clients.elasticsearch.core.DeleteByQueryRequest':

Response: 400 Bad Request
co.elastic.clients.util.MissingRequiredPropertyException: Missing required property 'ErrorResponse.status'

I checked it carefully and using application it works OK but using this embedded ES it doesn't.
I found information that I should add ReindexPluggin but unfortunately there is no implementation for ES 8.X here.
I found that for Netty4Plugin instead of old one there is a new project for 8.X version here.
Is there something similar for ReindexPlugin or am I doing something wrong here ?

Regards,
Fusiasty
