The backport to 2.17 failed:

The process '/usr/bin/git' failed with exit code 1

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-2.17 2.17
# Navigate to the new working tree
cd .worktrees/backport-2.17
# Create a new branch
git switch --create backport/backport-892-to-2.17
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 22f36c5f4f44d8efcd346f3cb7b40790e69dc4c8
# Push it to GitHub
git push --set-upstream origin backport/backport-892-to-2.17
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.17

Then, create a pull request where the base branch is 2.17 and the compare/head branch is backport/backport-892-to-2.17.

@martin-gaievski Let us observe the BWC Tests checks for 2.x and 2.17. I saw them failing mostly there

@martin-gaievski can you raise manual PR for 2.17?

[martin-gaievski]

this is for 2.17, I need to upport it to main and 2.x.
Sorry, I took a shortcut and started from 2.17 directly :)
