The backport to 1.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-1.x 1.x
# Navigate to the new working tree
pushd ../.worktrees/backport-1.x
# Create a new branch
git switch --create backport/backport-804-to-1.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 fdafe8b27ee8ad60359290939fdfd99a0ac859f8
# Push it to GitHub
git push --set-upstream origin backport/backport-804-to-1.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-1.x

Then, create a pull request where the base branch is 1.x and the compare/head branch is backport/backport-804-to-1.x.

@ryanbogan Publishing to sonatype has been successful. Publishing to maven local has some failures now :

> Task :generatePomFileForNebulaPublication FAILED

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':generatePomFileForNebulaPublication' (type 'GenerateMavenPom').
  - Gradle detected a problem with the following location: '/local/home/jpalis/repos/state/opensearch-sdk-java/build/distributions/opensearch-sdk-java-2.0.0-SNAPSHOT.pom'.
    
    Reason: Task ':publishMavenJavaPublicationToMavenLocal' uses this output of task ':generatePomFileForNebulaPublication' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
    
    Possible solutions:
      1. Declare task ':generatePomFileForNebulaPublication' as an input of ':publishMavenJavaPublicationToMavenLocal'.
      2. Declare an explicit dependency on ':generatePomFileForNebulaPublication' from ':publishMavenJavaPublicationToMavenLocal' using Task#dependsOn.
      3. Declare an explicit dependency on ':generatePomFileForNebulaPublication' from ':publishMavenJavaPublicationToMavenLocal' using Task#mustRunAfter.
    
    Please refer to https://docs.gradle.org/8.1.1/userguide/validation_problems.html#implicit_dependency for more details about this problem.
