Fix Issue #362: Comprehensive OpenAI Error Handling#646
Conversation
Replace silent failures with clear, actionable error messages to eliminate 90-minute debugging sessions when OpenAI API quota is exhausted. ## Backend Enhancements - Add error sanitization preventing sensitive data exposure (API keys, URLs, tokens) - Add upfront API key validation before expensive operations (crawl, upload, refresh) - Implement fail-fast pattern in RAG service (no more empty results for API failures) - Add specific error handling for quota, rate limit, auth, and API errors - Add EmbeddingAuthenticationError exception with masked key prefix support ## Frontend Enhancements - Create enhanced error utilities with OpenAI-specific parsing - Build TanStack Query compatible API wrapper preserving ETag caching - Update knowledge service to use enhanced error handling - Enhance TanStack Query hooks with user-friendly error messages ## Security Features - Comprehensive regex sanitization (8 patterns) with ReDoS protection - Input validation and circular reference detection - Generic fallback messages for sensitive keywords - Bounded quantifiers to prevent regex DoS attacks ## User Experience - Clear error messages: "OpenAI API quota exhausted" - Actionable guidance: "Check your OpenAI billing dashboard and add credits" - Immediate error visibility (no more silent failures) - Appropriate error severity styling ## Architecture Compatibility - Full TanStack Query integration maintained - ETag caching and optimistic updates preserved - No performance regression (all existing tests pass) - Compatible with existing knowledge base architecture Resolves #362: Users no longer experience mysterious empty RAG results that require extensive debugging to identify OpenAI quota issues. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Add detailed logging to API key validation function - Add debug logs to frontend error parsing - Add debug logs to TanStack Query error handler - This will help identify where error handling is failing in the UI
The embedding service wraps OpenAI AuthenticationError as EmbeddingAPIError, causing API key validation to fail silently instead of blocking operations. - Add specific handling for EmbeddingAPIError with 401 status codes - Detect authentication errors by checking for '401' and 'incorrect/invalid' keywords - Ensure API key validation properly blocks crawl operations - Add detailed logging to identify wrapped error types This fixes the issue where invalid API keys would start crawls that fail silently instead of showing immediate error messages in the UI.
The callAPIWithETag function extracts error messages from backend responses but loses the structured error details. Enhanced wrapper now reconstructs the full error structure based on status codes and error messages. - Add specific handling for ProjectServiceError class - Reconstruct OpenAI error details from extracted messages - Preserve error_type and structured message information - Add comprehensive debug logging to trace error parsing This ensures OpenAI authentication/quota errors are properly recognized and display the correct user-friendly messages in the UI.
Add comprehensive debug logs to parseKnowledgeBaseError to identify why OpenAI error details are not being recognized properly. This will show exactly what data structure is being received and why the error_type detection is failing.
Clean production-ready version with: - Comprehensive OpenAI error handling (401, 429, 502) - Proper error message sanitization - ProjectServiceError structure handling - Enhanced user-friendly error messages - TanStack Query integration Successfully resolves Issue #362 - users now get immediate clear error messages instead of silent failures and 90-minute debugging sessions.
Critical Issues Fixed: ✅ Remove hardcoded retry timing - use dynamic retry_after values ✅ Optimize regex patterns - use string operations + efficient patterns ✅ Improve error detection - use partial string matching instead of exact ✅ Fix exception swallowing - fail fast for config errors, allow network errors Improvements Added: ✅ Structured error codes (OPENAI_AUTH_FAILED, OPENAI_QUOTA_EXHAUSTED, etc.) ✅ Additional error types (timeout_error, configuration_error) ✅ Length limits on error messages (prevent processing large inputs) ✅ Enhanced user guidance for new error types ✅ Updated test assertions for error codes Security Enhancements: ✅ More efficient sanitization (string ops + simplified regex) ✅ Stricter bounds on regex patterns ✅ Input length validation The implementation now meets all production readiness criteria from the code review with robust error handling, enhanced security, and improved reliability for OpenAI error detection and user messaging.

Timestamp: 2025-08-28T13:07:24.810Z
Learning: The crawlProgressService.ts in the Archon codebase should be deprecated in favor of the existing useCrawlProgressPolling hook from usePolling.ts, which already includes ETag support, 304 handling, tab visibility detection, and proper React lifecycle integration. This consolidation reduces code duplication and improves performance.

python/src/server/api_routes/knowledge_api.py (4)
56-65: Well-designed provider-aware error sanitization.The
_sanitize_provider_errorfunction properly delegates to the ProviderErrorFactory for provider-specific sanitization, preventing information disclosure.
68-228: Comprehensive API key validation with excellent error handling.The
_validate_provider_api_keyfunction handles all edge cases well:
- Auto-detects provider from configuration
- Handles authentication, quota, and rate limit errors distinctly
- Provides clear, actionable error messages
- Allows network errors to pass through gracefully
- Fails fast for configuration errors
The error handling is thorough and user-friendly.
657-658: Good placement of API key validation checks.The CRITICAL comments and validation calls are properly placed before resource-intensive operations (refresh, crawl, upload).
Also applies to: 778-779, 934-935
1161-1247: Excellent provider-aware error handling in RAG endpoint.The error handling in
perform_rag_queryis comprehensive:
- Determines the current provider dynamically
- Handles each error type with appropriate HTTP status codes
- Provides provider-specific, sanitized error messages
- Includes relevant metadata in error responses
This implementation provides excellent user experience while preventing information leakage.

the Error and then casting it to EnhancedError (e.g., const enhancedError = new

🛠️ Refactor suggestion
Strengthen OpenAI error classification (use status/exception types; disambiguate 429 quota vs rate limit; 5xx handling).
Current string checks are brittle and may misclassify 429s and 5xx. Prefer introspecting status/exception names, fall back to message keywords, and include Retry-After when present. Also remove the redundant local import re.

python/src/server/services/embeddings/provider_error_adapters.py lines 51-90:
The current implementation relies on brittle string matching and a local "import
re"; update parse_error to first inspect standard attributes (e.g., status_code,
http_status, code) and exception class names to classify errors, disambiguate
429 responses by checking if the status/code equals 429 and then decide whether
it's quota (body indicates quota/credits/billing) or rate limit (Retry-After
present or typical rate-limit headers), treat 5xx status codes as
EmbeddingAPIError/TransientServerError, extract Retry-After and token counts
from structured fields when available (fall back to regex only as last resort),
and remove the inline import of re in favor of module-level import; populate the
specific adapter exceptions with api_key_prefix, tokens_used, retry_after, and
original_error as appropriate.

🛠️ Refactor suggestion
Make OpenAI key redaction length-agnostic (avoid false negatives).
Current logic assumes exactly 51 chars and tokenized-by-space; this can leak newer key formats or when punctuation is attached.

Add missing import for embedding exceptions.
The test uses EmbeddingAuthenticationError, EmbeddingQuotaExhaustedError, and EmbeddingAPIError in the _validate_provider_api_key tests but they're not imported at the top level in the knowledge_api.py file for these specific validation tests.
🏁 Script executed:

Add top-level imports for embedding exceptions. The exceptions are only imported inside an except block in python/src/server/api_routes/knowledge_api.py; move or add the import at module top-level so EmbeddingAuthenticationError, EmbeddingQuotaExhaustedError, and EmbeddingAPIError are available to the tests that reference them.

EmbeddingAuthenticationError, EmbeddingQuotaExhaustedError, and

so the test file can import them directly. Ensure the exceptions are exported
from their defining module and update any relative import paths in tests to
reference that top-level export.

Fix failing backend tests by updating test imports to use the new provider-agnostic function names: - _sanitize_openai_error → _sanitize_provider_error - _validate_openai_api_key → _validate_provider_api_key All test functionality preserved while supporting the new multi-provider error handling architecture. Tests now properly validate provider-agnostic error sanitization and API key validation.
