AttributeError: 'NoneType' object has no attribute '__version__'

I’m getting a strange error when trying to use community.general.gitlab_issue using ansible semaphore in a python virtual env

Semaphore is running as systemd service usiung .deb installation on ubuntu 22.04

# /etc/systemd/system/semaphore.service

ExecReload=/bin/kill -HUP $MAINPID

when I am entering the same virtual env that semaphore is using

semaphore@ansible:~$ virtualenv venv/

semaphore@ansible:~$ source /home/semaphore/venv/bin/activate
(venv) semaphore@ansible:~$ 

the playbook runs without any problem. But semaphore is getting just

/gitlab_issue.py", line 333, in main\nAttributeError: ‘NoneType’ object has no attribute ‘version’

So with other words, I cannot reproduce it. Any ideas what’s missing?

[markuman (Markus)]

Ok, I’ve found it. The semaphore task escaped from its virtual environment because of it’s inventory. It’s connected via ssh to localhost and took the environment from the host.

The module shouldn’t crash like this if python-gitlab isn’t installed. I’ve created a PR to fix that: gitlab modules: do not crash if python-gitlab isn't there by felixfontein · Pull Request #8158 · ansible-collections/community.general · GitHub - it will show a nicer message telling you that python-gitlab isn’t available.
