feat(AI GUI translations): Improved error handling

amilcarlucas · amilcarlucas · commit 90315ac5d9ea · 2025-09-15T17:56:07.000+02:00
🔧 Robust Output Validation
Added continue-on-error: true to the AI translation step so failures don't immediately break the workflow
Created a dedicated validation step (check_translation) that:
Checks if the AI translation step succeeded using ${{ steps.ai_translate.outcome }}
Validates that outputs exist before trying to use them
Provides detailed debugging information about available outputs
Sets flags indicating success/failure and preferred output method
🛡️ Better Error Handling
Added fallback behavior when AI translation fails:

Creates a placeholder file with failure markers
Continues the workflow instead of failing completely
Provides clear error messages and warnings
Enhanced the final processing step to:

Detect and count failed vs successful translations
Remove failed translation files before processing
Provide detailed reporting about success/failure rates
📊 Improved Reporting
Added comprehensive status reporting:

Individual job status reporting with warnings for failures
Summary statistics in the final PR
Clear documentation of what succeeded vs failed
Enhanced PR body with:

Translation processing summary
Quality assurance information
Details about error handling and robustness improvements
🔍 Debug Information
Added extensive debugging output:
Shows available action outputs
Validates file existence and content
Reports file sizes and line counts after successful translation
Provides step-by-step status information
Key Benefits:
No silent failures: The workflow will always report what happened
Graceful degradation: Failed translations don't break the entire workflow
Better visibility: Clear reporting of success/failure rates
Debugging support: Extensive logging to help troubleshoot issues
Validation: Checks outputs exist and are valid before using them
The workflow will now handle cases where:

The actions/ai-inference@v2 action fails completely
The action succeeds but provides unexpected output formats
Network issues cause intermittent failures
Rate limiting or quota issues with the AI service
File system issues with reading/writing translation files
This makes the workflow much more robust and production-ready!
