AAP 2.5, custom credential type, how-to for RPM installs?

I’m trying to install a custom cred type I’m building myself, into AAP 2.5 (non-containerized/non-operator arch).

The archived AWX process here, results in nothing new being added. I’m betting that I have a bug in my python.
Are awx-manage functions logged anywhere? I did search but did not find anyhting.

Will setup_managed_credential_types throw an error if the ‘install’ or ‘import’ fail?

My code tests fine manually.. I did use the AWX example above as my template but perhaps it’s out of date?

My code is here if it helps: delinea_auth_plugin/src/ss_token_plugin/plugin.py at main · cidrbl0ck/delinea_auth_plugin · GitHub
