Also this should go against main, and we can backport it after we're good there.

I really would like to add a test case. But unfortunately i'm not able to run the integration tests.
31 tests completed, 24 failed, 7 skipped

The AggregationRequestIT for example failes with this message:

java.lang.RuntimeException: found jar hell in test classpath
at org.opensearch.bootstrap.BootstrapForTesting.(BootstrapForTesting.java:118)
...

Any tips on how to fix this?

I'm running the tests in the shell with gradle.
I've noticed that the integration test for this MR is having the same trouble.
I encounter the same problems with the main branch as well without any changes from me.

You are very right, the issue seems to be caused by latest software.amazon.awssdk 2.20.141 (which is imported using version range). Created an issue for it here #615

I migrated the code changes to the main branch as dblock suggested.
I also added an Integration Test as reta suggested.
There is a new pull request #627 for the changes.
