Can't fetch remote repo changes: dubious ownership

[regisin]

I have a repo that builds static files and pushes to gh-pages (using hugo, not that it matters).

I have my script.sh like this:

#!/usr/bin/env sh

GIT_DIR=${1}
GIT_BRANCH=${2}
USER=${3}
EMAIL=${4}
HOME=${5}

# log date
echo "[redeploy] $(date):${USER}(${EMAIL})"

echo "git config --global --add safe.directory ${GIT_DIR}"
git config --global --add safe.directory ${GIT_DIR}

echo "git checkout ${GIT_BRANCH}"
git checkout ${GIT_BRANCH}

echo "git fetch origin"
git fetch origin

echo "git pull origin ${GIT_BRANCH}"
git pull origin ${GIT_BRANCH}

echo "git reset --hard origin/${GIT_BRANCH}"
git reset --hard origin/${GIT_BRANCH}

If I run webhook manually, all is good. However, when I try with the debian service, I get:

I have added user webhook to group ubuntu already to no avail (ubuntu owns "reponame" dir)
I'm confident it's a permission thing... I just can't seem to figure it out...

Would anyone help me?

Any help is appreciated!

I encountered the same issue previously, and once again with webhook, the tldr is to replace the config argument --global with --system:

git config --system --add safe.directory /home/ubuntu/static/reponame
