create folder adds [' my var ’]

[Gisbert Haas]

I have the following regex in my playbook:

   - name: get business ID

     set_fact:

       my_var: "{{ inventory_hostname | regex_findall('.+?(?=-).+?(?=-).+?(?=-).+?(?=-)+') }}"

the debug returns the right value:

ok: [DE-LEI-GRO-GROLE-F001-FW01-MDF] => {

    "my_var": [

        "DE-LEI-GRO-GROLE"

when using create directory

   - name: create directory

     file:

       path: /home/vinn/devicebackups/{{ my_var }}

       state: directory

its creates the directory adding [' ’]

"path": "/home/vinn/devicebackups/[''DE-LEI-GRO-GROLE’]",

any idea why??

thanks a lot

The bracket '[' tells us the variable my_var is a list. It's not
clear how the set_fact above managed to create the list.

The variable my_var is a list.

The filter regex_findall returns a list of matches

thanks

could it be that hyphen - are not allowed in the variable string?
