The backport to release/v1.7 failed:

Validation Failed: "Could not resolve to a node with the global id of 'T_kwDOAG3Mbc4AczmP'."

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new branch
git switch --create backport-3489-to-release/v1.7 origin/release/v1.7
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x 3d638098a3face9cdc9b9f833231e4718d428275

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-3489-to-release/v1.7
# Create the PR body template
PR_BODY=$(gh pr view 3489 --json body --template 'Backport 3d638098a3face9cdc9b9f833231e4718d428275 from #3489{{ "\n\n---\n\n" }}{{ index . "body" }}')
# Create the PR on GitHub
echo "${PR_BODY}" | gh pr create --title '[release/v1.7] [DOC] Fix broken links from doc 404 report' --body-file - --label 'type/docs' --label 'backport' --base release/v1.7 --milestone release/v1.7 --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-3489-to-release/v1.7

# Create a pull request where the `base` branch is `release/v1.7` and the `compare`/`head` branch is `backport-3489-to-release/v1.7`.

# Remove the local backport branch
git switch main
git branch -D backport-3489-to-release/v1.7
