Error blackbox_exporter_configuration_modules must be a string

[ns3777k]

What happened?

I installed the 0.9.3 role version, specify web listen address to be 127.0.0.1:9115 and after I ran a playbook, there was an error:

TASK [cloudalchemy.blackbox-exporter : configure blackbox exporter] ********************************************************************************************************************************************************************
fatal: [ax-monitoring]: FAILED! => {"changed": false, "msg": "AnsibleError: Unexpected templating type error occurred on (modules:\n  {{ blackbox_exporter_configuration_modules | to_nice_yaml(indent=2) | indent(2,False) }}\n): value must be a string"}

Did you expect to see some different?

Expected to see no errors.

How to reproduce it (as minimally and precisely as possible):

requirements.yml:

- name: cloudalchemy.blackbox-exporter
  version: '0.9.3'

playbook.yml:

- hosts: blackbox-exporter
  any_errors_fatal: True
  roles:
    - role: cloudalchemy.blackbox-exporter
      vars:
        blackbox_exporter_web_listen_address: "127.0.0.1:9115"

Run:

$ ansible-playbook -i inventories/remote.ini blackbox-exporter.yml

Environment

• Role version:

  0.9.3

• Ansible version information:

  2.9.16

• Variables:

blackbox_exporter_web_listen_address: "127.0.0.1:9115"

• Ansible playbook execution Logs:

TASK [cloudalchemy.blackbox-exporter : configure blackbox exporter] ********************************************************************************************************************************************************************
fatal: [ax-monitoring]: FAILED! => {"changed": false, "msg": "AnsibleError: Unexpected templating type error occurred on (modules:\n  {{ blackbox_exporter_configuration_modules | to_nice_yaml(indent=2) | indent(2,False) }}\n): value must be a string"}

Anything else we need to know?:

I tried to run this role without any variables and without any_errors_fatal: True, same result. I didn't find anything useful in issues. Thanks in advance.
