Code Review

This pull request correctly adds a type: ignore to handle an optional enterprise dependency during static analysis. My review includes one high-severity comment regarding the exception handling for this optional import. The current implementation uses a broad except Exception, which can hide bugs in the enterprise feature. I've recommended narrowing this to except ImportError for more robust error handling.
