@Arhell When you are running the script against your column branch, the script will fail to detect upstream changes because the file content/zh/docs/tasks/debug-application-cluster/debug-service.md in your column branch is already newer than the English file, aka, polluted. That is exactly the reason we are checking this for all PRs targeting the zh localization. If we merge this PR as is, we will forever lose track of the upstream changes that were not synced so far.

To make it clearer, please check the output from the master branch. Here is what I'm seeing:

git checkout master; git fetch upstream; git rebase upstream/master; git push
./scripts/lsync.sh content/zh/docs/tasks/debug-application-cluster/debug-service.md
