Problem Description

I tried to use opensearch instead elasticsearch with cortex but this cause errors

This is the configuration in opensearch.yml

this is my configuration with cortex in application.conf

I got these errors when I tried to reach the cortex page 127.0.0.1:9001

If I tried to change these values below in opensearch.yml i got this error

I changed the values from false to true

I got the next errors

Steps to Reproduce

Step 1 install opensearch version 1.3.11 and configure opensearch accordingly and run service Step 2 install cortex 3.1.7 latest version and configure cortex accordingly and run service Step 3 Try to open cortex in browser localhost:9001 and this cause error

Possible solutions

Maybe I think this is a problem with elastic4s and elastic4play libraries of cortex and this cause a problem with compatibility with opensearch, maybe these libraries needs to be change to have a compatibility with opensearch

Same for me here, always appear connection closed

That's a compatibility error, the workaround for this is to add this line to your elasticsearch.yml or opensearch.yml: compatibility.override_main_response_version: true

Be aware this can break connection between your indexer and other platforms. For example Graylog doesn't work if the compatibility override is set.
