Kubespray Helm role fails due to undefined variable download_defaults

[Tostaza]

I'm trying to use the helm-apps role in order to install a few applications with helm. The problem is that helm-apps uses the helm role as a dependency, which fails with the following error:

TASK [kubernetes-apps/helm : Download_file | Show url of file to dowload] *************************************************************************************************************************************** fatal: [node1]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: {{ download_defaults | combine(downloads.helm) }}: 'download_defaults' is undefined. 'download_defaults' is undefined. {{ download_defaults | combine(downloads.helm) }}: 'download_defaults' is undefined. 'download_defaults' is undefined\n\nThe error appears to be in '/home/kubespray/roles/download/tasks/download_file.yml': line 10, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Download_file | Show url of file to dowload\n ^ here\n"}

My playbook follows the example provided by the repo documentation (I'll place it here for accessibility) and is executed at the end of all the cluster deployment (cluster.yml):

---
- hosts: kube_control_plane[0]
  gather_facts: no
  roles:
    - name: helm-apps
      releases:
        - name: app
          namespace: app
          chart_ref: simple-app/simple-app
        - name: app2
          namespace: app
          chart_ref: simple-app/simple-app
          wait_timeout: "10m" # override the same option in `release_common_opts`
      repositories: "{{ repos }}"
        - name: simple-app
          url: "https://blog.leiwang.info/simple-app"
      release_common_opts: "{{ helm_params }}"
        wait_timeout: "5m"

If I comment the dependency lines in helm-apps/meta/main.yaml, everything works well.

I hope you can help me as I'm starting with Ansible and Kubespray and this problem has been bugging me for days. Thank you in advance!
