Jinja spacing error

Nothing can be more frustrating as receiving a jinja spacing error while linting your code. . You know that there is nothing wrong with it, it runs without any errors and still every time you run the linter, this error pops up: Improve jinja spacing....

The code:

  - name: Add the controller to the names of the templates
    ansible.builtin.set_fact:
      ee_on_templates: >-
        [
        {%- for i in range(_template_list | length) -%}
        '{{ inventory_hostname }}   {{ i }}'
        {%- if not loop.last -%},
        {%- endif -%}
        {%- endfor -%}
        ]

In the above code, we did everything to remove spaces... like {%- -%} and still the linter complains.

It looks like valid code, and it is... But:

WARNING  Listing 1 violation(s) that are fatal
jinja[spacing]: Jinja2 spacing could be improved: [ {%- for i in range(_template_list | length) -%} '{{ inventory_hostname }}   {{ i }}' {%- if not loop.last -%}, {%- endif -%} {%- endfor -%} ] -> [{%- for i in range(_template_list | length) -%} '{{ inventory_hostname }}   {{ i }}'{%- if not loop.last -%},{%- endif -%} {%- endfor -%} ] (warning)
check_data.yml:84 Jinja2 template rewrite recommendation: `[{%- for i in range(_template_list | length) -%} '{{ inventory_hostname }}   {{ i }}'{%- if not loop.last -%},{%- endif -%} {%- endfor -%} ]`.

The final trick is not to try to ignore the error, but change the set_fact ever so slightly:

  - name: Add the controller to the names of the templates
    ansible.builtin.set_fact:
      ee_on_templates: >-
        [
        {%- for i in range(_template_list | length) -%}
        '{{ inventory_hostname }}   {{ i }}'
        {%- if not loop.last -%},
        {%- endif -%}
        {%- endfor -%}
        ]

The | instead of > makes all the difference..
