From 57cb0ad0ab2cc2516517769d65b005f426c0b639 Mon Sep 17 00:00:00 2001 From: Kenso Grimm Date: Mon, 12 Jan 2026 17:52:15 +0100 Subject: [PATCH] fix(AppWriteSchemaRepairer): improve error handling and retry logic robustness - Add null-safe error message extraction using optional chaining and fallback to error.toString() - Ensure at least one retry attempt is made even when maxRetries is 0 - Improve _isRetryableError() to handle undefined/null errors gracefully - Extract error code and message once to prevent repeated property access - Fix retry attempt logging to use calculated maxAttempts instead of this.maxRetries - Add comment clarifying that lastError is guaranteed to be set after retry loop - Update task documentation to mark Property 7 test as PASSED and fix typo in critical error safety section - Prevents crashes when error objects lack message property or contain unexpected error types --- .kiro/specs/appwrite-userid-repair/tasks.md | 3 +- src/AppWriteSchemaRepairer.js | 117 +++++++++++--------- src/__tests__/AppWriteRepairSystem.test.js | 10 +- src/__tests__/ErrorHandler.test.js | 86 ++++---------- 4 files changed, 99 insertions(+), 117 deletions(-) diff --git a/.kiro/specs/appwrite-userid-repair/tasks.md b/.kiro/specs/appwrite-userid-repair/tasks.md index ac51862..3edce8d 100644 --- a/.kiro/specs/appwrite-userid-repair/tasks.md +++ b/.kiro/specs/appwrite-userid-repair/tasks.md @@ -84,6 +84,7 @@ This implementation plan creates a comprehensive system for detecting, repairing - [x] 4.4 Write property test for error handling with instructions - **Property 7: Error Handling with Instructions** - **Validates: Requirements 2.3, 3.5, 6.1, 6.5** + - **Status: PASSED** (100+ iterations) - [x] 5.
