I am trying to deploy [confluentinc-kafka-connect-elasticsearch](https://www.confluent.io/hub/confluentinc/kafka-connect-elasticsearch), however, I got error

> Connector version 11.1.8 is not compatible with Elasticsearch version 1.2.4. Elasticsearch version must be at least 7.0.0.

I tried to find a version compatibility table online, but didn’t find.  
I am wondering how to find which version is compatible with OpenSearch 1.2.4? Thanks!

I am having same error with different version. Looks like its just a version check which is now 1.1 instead of 7.x. Is there any way in OpenSearch to respond with last compatible elastic version?

Hi,

You may need to configure the compatibility setting [1], so the connector would get the recognizable version:

```auto
PUT _cluster/settings
{
  "persistent": {
    "compatibility": {
      "override_main_response_version": true
    }
  }
}

```
