get_url zero’s the file on second run.

  • I run a playbook which downloads and runs a command file.
  • get_url works perfectly 1st time
  • I run the same playbook a second time and the downloaded file now has 0 size

ansible version info:
ansible [core 2.14.18] config file = /root/ansible.cfg configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python3.9/site-packages/ansible ansible collection location = /root/.ansible/collections:/usr/share/ansible/collections executable location = /usr/bin/ansible python version = 3.9.21 (main, Jun 27 2025, 00:00:00) [GCC 11.5.0 20240719 (Red Hat 11.5.0-5)] (/usr/bin/python3) jinja version = 3.1.2 libyaml = True
