Where you are defining the template task you should put double quotes round
the jina code
e.g "{% for i in item.config_files %} src={{i}}.j2 dest={{item.FS}}/{{i}}
{% endfor %}" otherwise the jinja syntax will not be evaluated.
I have however never used a for loop in this fashion so no idea if that
will work, I would be interested to hear if it does.
Kind Regards
