ElasticsearchAsyncSearchClient: Error Responses can't be deserialized #674
Description
Java API client version
8.7.1
Java version
17
Elasticsearch Version
8.7.1
Problem description
The ElasticsearchAsyncSearchClient expects ErrorResponse in case of an issue.
ErrorResponse has status as a required property but the Elasticsearch error response for asyncSearch requests doesn't have a status -> ErrorResponse can't be deserialized. Instead the Endpoint's ResponseType is returned (if this can be deserialized) and the actual issue is suppressed.

Hello, thanks for reporting this! I tried to reproduce this, but I'm getting the same errors both with the synchronous client and the asynchronous client. If this is still an issue, could you provide an example of this behaviour? Thank you.

Which version did you test? I still see issues (different ones, as for 8.7.1) with version 8.12.2.
The response from es contains more than just error or status, which could be read by co.elastic.clients.transport.endpoints.EndpointBase#errorDeserializer
