No session role

Error message

No session role

What it means

Raised by role_info() when a session is active but the session has no role name set (session.role_name() returns None). The export of a session-derived role is impossible without an assigned role, so the function bails instead of exporting an empty configuration.

Solutions

1. Set a role on the session before requesting role information
2. Use the default/global role info instead by exiting the session
3. Initialize the session with an explicit role
