# GOOGLE_SERVICE_ACCOUNT_CREDENTIALS is a string with JSON in it (curly-braces).
# secret-vars assume that curly-braces in environment variables contain values that will be replaced.
# So it fails because JSON contains double-quotes within the curly-braces.
# 
# The only change to this flie is the line that comments ". secret-vars"
