# cat /tmp/webhook-env.log

Issue

There are no variables HOME, USER. Git can not clone/pull repositories with save authorization from github.

Solution

Case 1: Add variables in script

export HOME=/root
export USER=root

Case 2: Use .env file

# cat .env
HOME=/root
USER=root

# in script
set -a
source .env
