pass wordlists as variables in templates

[hugo-syn]

Hello I would like to create a template for BF login panel with my own wordlist on my system but I can make it work like this:

http:
  - raw:
      - |
        POST /login.php HTTP/1.1
        Host: {{Hostname}}
        Content-Type: application/x-www-form-urlencoded

        user={{username}}&passwd={{password}}

    attack: clusterbomb
    payloads:
      username: "{{BF_USERNAMES}}"
      password: "{{BF_PASSWORDS}}"

    matchers-condition: and
    matchers:
      - type: word
        part: header
        words:
          - "Set-Cookie: PHPSESSID"

      - type: status
        status:
          - 200

nuclei -t ./ -u https://127.0.0.1/ -verbose -var "BF_USERNAMES=/path/to/users.txt" -var "BF_PASSWORDS=/path/to/passwords.txt"
[WRN] Could not parse template /.../bf.yaml: could not compile request: could not parse payloads: the {{BF_USERNAMES}} file for payload username does not exist or does not contain enough elements
