The backport to release-2.6.x 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 branch
git switch --create backport-6477-to-release-2.6.x origin/release-2.6.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x da3fbd965bd4d1f31130dacaa2d1e1dff388321f
# Push it to GitHub
git push --set-upstream origin backport-6477-to-release-2.6.x
git switch main
# Remove the local backport branch
git branch -D backport-6477-to-release-2.6.x

Then, create a pull request where the base branch is release-2.6.x and the compare/head branch is backport-6477-to-release-2.6.x.
