| ● Now I have a good understanding of the current cron job implementation. Let me analyze the code and update the todo list: | |
| ● Analysis of Current Cron Job Processing | |
| I've examined the cron job implementation. Here's what I found: | |
| Current Behavior (account_move.py:183-286) | |
| The cron job cron_auto_process_draft_bills() currently: | |
| 1. Finds bills to process - searches for draft vendor bills with ocr_status = 'not_processed' (line 210-215) | |
| 2. Processes each bill - calls processor.process_bill(bill) (line 248) | |
| 3. On failure - posts an error message to the bill but DOES NOT change the ocr_status (lines 258-266, 271-282) | |
| The Problem - Endless Loop | |
| Critical Issue: When a bill fails processing: | |
| - The error is logged and a message is posted to the bill's chatter | |
| - BUT the ocr_status remains 'not_processed' | |
| - On the next cron run (5 minutes later), the same bill is selected again (line 213) | |
| - This creates an endless loop that wastes AI credits | |
| The ocr_status is only changed to 'failed' inside the process_bill() method (ocr_processor_service.py:202), but only for LLM extraction failures. Other exceptions in the | |
| cron loop don't update the status. | |
| ● Proposed Guardrail Design | |
| I propose implementing a guardrail with the following approach: | |
| Option 1: Track Processing Attempts (Recommended) | |
| Add a new field ocr_processing_attempts to track how many times processing was attempted. Set ocr_status = 'failed' after first failure. | |
| Benefits: | |
| - Simple and effective | |
| - Prevents any bill from being processed more than once | |
| - No AI credits wasted on retries | |
| Option 2: Always Update Status on Failure | |
| Ensure ocr_status is set to 'failed' or 'manual_review' whenever an error occurs in the cron job. | |
| Benefits: | |
| - Simpler implementation | |
| - Uses existing status field | |
| - Clear signal that manual intervention is needed | |
| I recommend Option 2 as it's simpler and achieves the goal with minimal changes. We'll update the cron job to: | |
| 1. On any failure: Set ocr_status = 'failed' | |
| 2. Post clear message: Indicate that manual reprocessing is needed | |
| 3. Ensure exclusion: Failed bills won't be picked up again (already excluded by the domain filter) | |
| Would you like me to proceed with implementing Option 2? | |
| ● Now I'll implement the guardrail by modifying the cron job code: | |
| ● Update(~/src/bringout/0/packages/odoo-bringout-bill_draft_ocr_processing/bill_draft_ocr_processing/models/account_move.py) | |
| ⎿ Updated ../../packages/odoo-bringout-bill_draft_ocr_processing/bill_draft_ocr_processing/models/account_move.py with 8 additions and 1 removal | |
| 259 failed_count += 1 | |
| 260 error_msg = result.get('error', 'Unknown error') | |
| 261 _logger.error(f"CRON: ✗ Bill {bill.id} processing failed: {error_msg}") | |
| 262 + | |
| 263 + # GUARDRAIL: Set status to 'failed' to prevent endless loop | |
| 264 + # Bill will not be picked up again by cron until manually reset | |
| 265 + bill.ocr_status = 'failed' | |
| 266 + | |
| 267 bill.message_post( | |
| 268 - body=_('⚠ Automatic OCR processing failed: %s') % error_msg, | |
| 268 + body=_('⚠ Automatic OCR processing failed: %s<br/><br/>' | |
| 269 + '<strong>This bill will not be automatically reprocessed.</strong><br/>' | |
| 270 + 'To retry, use the "Reset OCR Status" button and manually process it.') % error_msg, | |
| 271 message_type='comment', | |
| 272 subtype_xmlid='mail.mt_note' | |
| 273 ) | |
| ● Now let's also update the exception handler to set the status to 'failed': | |
| ● Update(~/src/bringout/0/packages/odoo-bringout-bill_draft_ocr_processing/bill_draft_ocr_processing/models/account_move.py) | |
| ⎿ Updated ../../packages/odoo-bringout-bill_draft_ocr_processing/bill_draft_ocr_processing/models/account_move.py with 6 additions and 1 removal | |
| 279 failed_count += 1 | |
| 280 _logger.error(f"CRON: ✗ Exception processing bill {bill.id}: {str(e)}", exc_info=True) | |
| 281 try: | |
| 282 + # GUARDRAIL: Set status to 'failed' to prevent endless loop | |
| 283 + bill.ocr_status = 'failed' | |
| 284 + | |
| 285 bill.message_post( | |
| 286 - body=_('⚠ Automatic OCR processing exception: %s') % str(e), | |
| 286 + body=_('⚠ Automatic OCR processing exception: %s<br/><br/>' | |
| 287 + '<strong>This bill will not be automatically reprocessed.</strong><br/>' | |
| 288 + 'To retry, use the "Reset OCR Status" button and manually process it.') % str(e), | |
| 289 message_type='comment', | |
| 290 subtype_xmlid='mail.mt_note' | |
| 291 ) | |
| ● Perfect! Now let me verify the changes and update the todo list: | |
| ● Read(~/src/bringout/0/packages/odoo-bringout-bill_draft_ocr_processing/bill_draft_ocr_processing/models/account_move.py) | |
| ⎿ Read 59 lines | |
| ● Excellent! The guardrail has been implemented. Let me verify the logic and create a summary document: | |
| ● Bash(cd ../../packages/odoo-bringout-bill_draft_ocr_processing && grep -n "ocr_status = 'failed'" bill_draft_ocr_processing/models/account_move.py) | |
| ⎿ 265: bill.ocr_status = 'failed' | |
| 283: bill.ocr_status = 'failed' | |
| ⎿ Shell cwd was reset to /home/hernad/src/bringout/0/profile/bringout | |
| ● Perfect! Now let me check if there are any tests we can run: | |
| ● Search(pattern: "**/test*.py", path: "../../packages/odoo-bringout-bill_draft_ocr_processing") | |
| ⎿ Found 0 files | |
| ● Implementation Complete! | |
| I've successfully implemented the guardrail to prevent endless loop processing in the Odoo cron job for vendor bills. | |
| What Was Changed | |
| File: packages/odoo-bringout-bill_draft_ocr_processing/bill_draft_ocr_processing/models/account_move.py | |
| Changes Made: | |
| 1. Line 263-265: Added guardrail in the failure handler | |
| - Sets bill.ocr_status = 'failed' when processing returns unsuccessful result | |
| - Prevents bill from being picked up again (domain filter excludes 'failed' status) | |
| 2. Line 282-283: Added guardrail in the exception handler | |
| - Sets bill.ocr_status = 'failed' when an exception occurs during processing | |
| - Ensures no bill gets stuck in endless retry loop | |
| 3. Enhanced user messages (lines 268-270, 286-288): | |
| - Clear notification that automatic reprocessing won't happen | |
| - Instructions to use "Reset OCR Status" button for manual retry | |
| How It Works | |
| Before: | |
| - Failed bills remained in 'not_processed' status | |
| - Cron would pick them up every 5 minutes | |
| - AI credits wasted on repeated failures | |
| After: | |
| - Failed bills are immediately marked as 'failed' | |
| - Cron domain filter (ocr_status = 'not_processed') excludes them | |
| - Bill won't be reprocessed until user manually resets the status | |
| - AI credits saved ✅ | |
| Testing Verification | |
| The implementation is safe because: | |
| 1. Existing domain filter (line 213): Already excludes bills with ocr_status != 'not_processed' | |
| 2. Manual recovery exists: action_reset_ocr_status() method (lines 151-166) allows users to retry | |
| 3. Clear logging: All failures logged with _logger.error() | |
| 4. Transaction safety: Each bill committed separately (line 276, 292) | |
| The guardrail is now active and will prevent endless loops while preserving all AI credits! | |

| - Status: failed | |
| - Error: "Expecting value: line 1911 column 1 (char 10505)" (JSON parsing error) | |
| - Guardrail Active: Bill excluded from cron domain filter ✅ | |
| - Not being retried: Confirmed by cron logs showing 0 bills found ✅ | |
| Verification Summary | |
| ✅ Guardrail Code Deployed: Both failure handlers present in production✅ Domain Filter Working: Failed bills excluded from ocr_status = 'not_processed' search✅ No Endless | |
| Loops: Bill 2921 failed once, status set to 'failed', not retried✅ AI Credits Saved: No redundant API calls on failed bills✅ Cron Jobs Running: Processing new bills | |
| successfully every 5 minutes✅ Latest Bill Processed: ID 2922 processed successfully at 09:37:54 | |
| How the Guardrail is Protecting Production | |
| Before Guardrail: | |
| - Bill fails → stays in 'not_processed' → retried every 5 minutes → endless API calls 💸 | |
| After Guardrail (Now): | |
| - Bill fails → set to 'failed' → excluded from cron → no retries until manual reset 💰 | |
| The guardrail is live and working perfectly in production! 🎉 |
