git_retrieve with empty known_hosts file in EE runs into timeout on AAP

[PostChrO]

SUMMARY

I am trying to use ansible.scm in an AAP Execution Environment to retrieve a git repository via SSH. When calling git_retrieve the execution stops, asking what to do about the new unknown hostkey. Afterwards the execution is aborted due to a timeout waiting for a console input.
I tried adding 'host_key_checking: "no"' to the task, but this did not change anything. I guess git_publish will have the same problem.

COLLECTION VERSION

Collection  Version
----------- -------
ansible.scm 1.1.0

CONFIGURATION

CONFIG_FILE() = /etc/ansible/ansible.cfg

OS / ENVIRONMENT

Ansible Automation Platform Controller 4.3.8
The execution environment uses "Red Hat Enterprise Linux release 8.8 (Ootpa)"

STEPS TO REPRODUCE

Launch a Job Template in an execution environment which does not have any SSH known_hosts file.

---
- name: "ansible.scm tests"
  hosts: localhost
  gather_facts: false
  collections:
    - ansible.scm
  tasks:
    - name: "Retrieve Task"
      ansible.scm.git_retrieve:
        host_key_checking: "no"
        origin:
          url: ssh://git@gitithost/projectname/reponame.git
      register: repository

EXPECTED RESULTS

The expectation is, that the given git repo is checked out into a temporary directory inside the execution environment accepting/ignoring the unknown host key. The same way as the "accept_hostkey: true" option of ansible.builtin.git is working.

ACTUAL RESULTS

The execution got stuck at the ssh prompt asking wether to accept the unknown host key. Finally running into a timeout as no answer is given.
Although not tested, I assume git_publish will have the same problem.

My main reason I am trying to use ansible.scm is the git_publish functionality.

As a workaround I could use a dummy ansible.builtin.git with the "accept_hostkey: true" option, to add the git server's fingerprint to the ~/.ssh/known_hosts file in the EE, and afterwards use ansible.scm.*

Have you tried this with host_key_checking: accept-new. That seems to work for me.
