The codecov/codecov-action was changed to v3 as the opensearch-project/opensearch-build/.github/workflows/get-ci-image-tag.yml@main was changed back to CentOS7 (Related PR, Related opensearch-project/opensearch-build#4379), the v4 works with no problem with almalinux8.

Error when used v4 and with CentOS7.

Yes @prudhvigodithi expected behavior as CentOS7 does not support node16 or up.
