The backport to v11.0.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-87538-to-v11.0.x origin/v11.0.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x 3a2c9f4898cee953f8b689ef3488583955a15a6c

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-87538-to-v11.0.x
# Create the PR body template
PR_BODY=$(gh pr view 87538 --json body --template 'Backport 3a2c9f4898cee953f8b689ef3488583955a15a6c from #87538{{ "\n\n---\n\n" }}{{ index . "body" }}')
# Create the PR on GitHub
echo "${PR_BODY}" | gh pr create --title "[v11.0.x] alerting: integrations > small update" --body-file - --label "type/docs" --label "no-changelog" --label "backport" --base v11.0.x --milestone 11.0.x --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-87538-to-v11.0.x

# Create a pull request where the `base` branch is `v11.0.x` and the `compare`/`head` branch is `backport-87538-to-v11.0.x`.

# Remove the local backport branch
git switch main
git branch -D backport-87538-to-v11.0.x
