Expected behavior

It should work with a message Commit not needed
No issues when modification are there to commit to the device.

Current behavior

Python error

 commit_response_msg = commit_response.find(\"./msg/line\").text\nAttributeError: 'NoneType' object has no attribute 'text'\n",

Possible solution

Change line on /panos/base.py (https://github.com/PaloAltoNetworks/pan-os-python/blob/62bcff3bca86a5ff745eae3e92635d109673963a/panos/base.py#L4906C1-L4906C78)

to add a try except

                try:
                    commit_response_msg = commit_response.find("./msg/line").text
                except AttributeError:
                    commit_response_msg = "No message in commit response"
                self._logger.debug("No job id. Msg: " + commit_response_msg)

Steps to reproduce

1. Commit without changes

Start in panos/base.py at _commit around the commit_response.find("./msg/line") call. Reproduce by committing without changes through the Ansible panos_commit_panorama module, then verify the no-change response is handled without an AttributeError and reports that no commit is needed.
