@jasonmlkang I tried testing the GUI but Python complained:

2022-08-05T13:57:59.039 | ERROR    | <class 'ModuleNotFoundError'> creating plugin 0: No module named 'ait.gui'
2022-08-05T13:57:59.040 | WARNING  | No valid plugin configurations found. No plugins will be added.

For my environment:

1. I am creating a venv via: python3 -m venv venv
   ...and then activating it via: source venv/bin/activate.csh

2. I then git-cloned and poetry-installed the two AIT projects.
   No issues when running poetry on those.

3. After that I set AIT_CONFIG and then added the GUI plugin config to it.

4. Finally I ran: ./AIT-Core//ait/core/bin/ait_server.py

This is similar to issues I was having before when poetry and pip were mixed, and ait.core module could not be found.
Anyhoot, the environment setup is relatively bare-bones (vs Conga, etc), so I would expect it to work.

Could you please give it a whirl and see what might need to be resolved? Thanks

Not sure if this info helps:

[venv] MT-202661{nttoole}% ls ./venv/lib/python3.7/site-packages/ait*
ait/                            ait_core-2.3.5.dist-info/       ait_core.pth                    ait_gui.pth 
ait_core-2.3.5-py3.7-nspkg.pth  ait_core-2.3.6rc1.dist-info/    ait_gui-2.3.2rc1.dist-info/

Merging this as is and will address other packaging updates in follow on tickets. Looks like this is working fine but could be wrong. Willing to let this break stuff temporarily so work can carry on.

Thanks @jasonmlkang!!
