The backport to main 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-18680-to-main origin/main
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x b4075c0a307b68183366d9a2d618948199135e67

When the conflicts are resolved, stage and commit the changes:

git add . && git cherry-pick --continue

If you have the GitHub CLI installed:

# Push the branch to GitHub:
git push --set-upstream origin backport-18680-to-main
# Create the PR body template
PR_BODY=$(gh pr view 18680 --json body --template 'Backport b4075c0a307b68183366d9a2d618948199135e67 from #18680{{ "\n\n---\n\n" }}{{ index . "body" }}')
# Create the PR on GitHub
echo "${PR_BODY}" | gh pr create --title 'chore(release-3.5.x): release 3.5.4 (backport main)' --body-file - --label 'size/S' --label 'product-approved' --label 'autorelease: pending' --label 'backport' --base main --milestone main --web

Or, if you don't have the GitHub CLI installed (we recommend you install it!):

# Push the branch to GitHub:
git push --set-upstream origin backport-18680-to-main

# Create a pull request where the `base` branch is `main` and the `compare`/`head` branch is `backport-18680-to-main`.

# Remove the local backport branch
git switch main
git branch -D backport-18680-to-main
