Fixed critical authentication issue causing "user does not exist [uid: 0]" errors during metadata mirroring operations. This release addresses Issue #68 and ensures proper authentication validation before all Gitea operations.
Key improvements:
- Pre-flight authentication validation for all Gitea operations
- Consistent token decryption across all API calls
- Repository existence verification before metadata operations
- Graceful fallback to user account when org creation fails
- Enhanced error messages with specific troubleshooting guidance
- Added diagnostic test scripts for authentication validation
This patch ensures metadata mirroring (issues, PRs, labels, milestones) works reliably without authentication errors.
