Error listings
Fix unreliable error classification in OpenAI Python SDK when using /v1/responses background mode; needs stable error.type field mapped to SDK exception classes for proper retry logic Includes evidence for OpenAI API troubleshooting demand.
HTTP 200 OK poll returns error.code='server_error' with status='failed', no typed exception raised — retry/backoff logic cannot distinguish server_error vs rate_limit_exceeded Fix GitHub MCP authentication failure on Claude Code web (remote/cloud sessions) Includes evidence for Claude Code troubleshooting demand.
HTTP 403 "unauthorized: not authorized to use this Copilot feature" Prevent LangChain from retrying insufficient_quota errors instead of surfacing billing fix prompt to user Includes evidence for LangChain troubleshooting demand.
OpenAI insufficient_quota errors mistaken for rate limits causing unnecessary retries Distinguish between LiteLLM proxy rate limiting and underlying OpenAI quota exhaustion for faster fix Includes evidence for LiteLLM troubleshooting demand.
litellm.RateLimitError: RateLimitError: OpenAIException - Error code: 429 - { 'error' : {'message': 'You exceeded your current quota , please check your plan and billing details.'} Fix Vercel deploy failure caused by tsconfig path aliases not resolving correctly in build container Includes evidence for Vercel troubleshooting demand.
Module not found: Can't resolve '<component>' on Vercel despite working locally (shadcn-ui path alias issue) Fix Claude Code failing to persist OAuth tokens for custom MCP connectors across sessions, forcing manual restart via /exit and claude mcp list Includes evidence for Claude Code troubleshooting demand.
[BUG] Custom MCP connector OAuth tokens fail to persist — quarri MCP server requires /exit then claude mcp list workaround Fix GitHub Copilot getting stuck in sign-in loop in VS Code after cache corruption or credential mismatch; unable to activate extension Includes evidence for GitHub Copilot troubleshooting demand.
GitHub Copilot sign-in button not responding / stuck in sign-in loop — authentication provider registration timed out Fix Claude Code silently failing when HTTP MCP servers need OAuth auth but haven't been completed — zero feedback that something went wrong Includes evidence for Claude Code troubleshooting demand.
[BUG] HTTP MCP servers requiring OAuth silently fail with no tools shown when user hasn't completed authentication Configure automatic fallback to secondary models when primary model group hits LiteLLM rate limits; avoid downtime on paid proxy tier Includes evidence for LiteLLM troubleshooting demand.
RateLimitError: Rate limit exceeded — LiteLLM proxy needs automatic fallback configuration for model groups to handle rate limit errors gracefully Fix LiteLLM hanging 600 seconds on Ollama connection timeout instead of raising proper error quickly; understand why stream_timeout and regular timeout settings don't work for watsonx/Ollama backends Includes evidence for LiteLLM troubleshooting demand.
ERROR :root: LiteLLM call failed: litellm.APIConnectionError: OllamaException - litellm.Timeout: Connection timed out after 600.0 seconds. Fix Claude Code MCP OAuth tokens stored correctly but reconnection fails, tools not appearing until manual restart of Claude Code Includes evidence for Claude Code troubleshooting demand.
OAuth Authentication Succeeds but MCP Reconnection Fails — tools remain missing after manual restart required Fix LiteLLM proxy rate limit error that leaks internal API key SHA-256 hash in error message body, exposing credentials Includes evidence for LiteLLM troubleshooting demand.
Error: { "message": "Rate limit exceeded for ...", ... } leaking full SHA-256 key in response body Fix LiteLLM hiding 429 rate limit errors from Vertex AI during streaming requests; clients see hung responses instead of actionable error Includes evidence for LiteLLM troubleshooting demand.
Vertex AI 429 rate limit error during streaming not surfaced to client — only visible in LiteLLM debug logs, causes silent streaming failures Fix complete model failure in Claude Code where all Anthropic Sonnet models return exit code 1, blocking all AI-assisted coding sessions Includes evidence for Claude Code (Anthropic) troubleshooting demand.
Command failed with exit code 1 for all sonnet models via Claude Code API Provider Fix reasoning/function_call pairing errors when using GPT-5 series models through Cline MCP integration Includes evidence for Cline (Claude Code) troubleshooting demand.
reasoning/function_call pairing error during MCP/tool use on gpt-5.3-codex, gpt-5.4, gpt-5.5 Fix Pydantic validation errors when Cline passes task_progress parameter to Jira MCP tool calls, blocking automated task management workflows Includes evidence for Cline (Claude Code) troubleshooting demand.
Pydantic ValidationError: task_progress parameter incorrectly passed to MCP tool calls Resolve discrepancy in how rate limit errors are returned by different OpenAI APIs so developers can handle throttling uniformly Includes evidence for OpenAI API troubleshooting demand.
Inconsistent rate limit error responses between Responses API and Chat Completions API Fix or understand timeout errors occurring when LiteLLM proxy forwards requests to upstream LLM providers, causing cascading failures in production Includes evidence for LiteLLM troubleshooting demand.
TimeoutError / Timeout on upstream API provider calls through LiteLLM proxy Fix type serialization bug where Cline sends numeric and boolean parameters as strings to MCP servers, causing client-side validation failures Includes evidence for Cline (Claude Code) troubleshooting demand.
Zod literal validation failures: MCP tool parameters with integer/boolean types are sent as strings Fix quota/rate-limit mismatch where ChatGPT Plus OAuth authenticates but downstream Codex/API calls get blocked by 429 rate limits Includes evidence for OpenAI API troubleshooting demand.
OAuth succeeds but third-party calls return 429 quota exceeded
