[staging-kestrelai-security]

Automated code fix for incident f699bfda-92b3-4da5-8e6f-f015853901ff.

Files changed:

• services/profile_service.py: Added a null check for the user object after fetching it. If user is None, the function logs a warning and returns None, preventing AttributeError when accessing user attributes.
• main.py: Added a check for None after calling get_enriched_profile. If the profile is None, log a warning instead of trying to access its attributes.
