Galaxy-NG installation issue

Hello,
I’m installing Galaxy-NG using the following documentation (Installation - Galaxy NG), but when I run the “docker run …” command I get the following error in the deployment logs. “ImportError: Could not import ‘galaxy_ng.app.auth.session.SessionAuthentication’ for API setting ‘DEFAULT_AUTHENTICATION_CLASSES’. ModuleNotFoundError: No module named ‘galaxy_ng.app.auth.session’”
I’ve tested the installation with several Galaxy-NG versions provided by quay.io and always get the same result.

Thanks in advance for your help.
Best regards,
