Attaching files with the Ansible Jira module

[Necati Karyeli]

Hi, 
Does anyone has any experience with attaching files with the Ansible Jira module?

I have tried the following but it returns HTTP Error 400

other operations like transition and comment are working fine

- name: 'attachment Jira'
local_action:
module: jira
uri: "{{jira URL}}"
username: "{{{{ jirauser }}}}"
password: "{{{{ password_jira}}}}"
issue: "{{ticketnr}}"
operation: edit
args:
fields:
attachment:
filename: "output_unzip.txt"
