Needs opensearch-project/OpenSearch#18933

Let me know if we can run

./gradlew wrapper --gradle-version 8.14.3 --distribution-type all --gradle-distribution-sha256-sum ed1a8d686605fd7c23bdf62c7fc7add1c5b23b2bbc3721e661934ef4a4911d7c

We could do that as well, sure, the opensearch-project/OpenSearch#18933 would have to be merged anyway

@reta Looks like codecov did not run. Can you please check? Looks like something related to https://github.com/opensearch-project/custom-codecs/blob/main/.github/workflows/check.yml#L37 ?
