Bedrock streaming SSE events errors are not handled gracefully LiteLLM LiteLLM Updated May 21, 2026
Fix GCP IAM authentication failure when running LiteLLM proxy with Redis Cluster — the sync auth path creates a standalone redis client via redis_connect_func that doesn't participate in Redis Cluster topology Includes evidence for LiteLLM troubleshooting demand.
GCP IAM auth fails with Redis Cluster — sync path uses redis_connect_func which RedisCluster bootstrap ignores LiteLLM LiteLLM Updated May 21, 2026

Fix missing usage/spend tracking in LiteLLM proxy when upstream provider (e.g., Ollama Cloud) returns duplicate response IDs causing log collision Includes evidence for LiteLLM troubleshooting demand.
Spend logs silently dropped when provider returns non-unique response IDs (Ollama Cloud) OpenAI API OpenAI API Updated May 21, 2026
Add stable error code/classification for OpenAI Responses API background task failures so clients can handle retries differently Includes evidence for OpenAI API troubleshooting demand.
Background responses API errors do not map to a stable exception class name, making client-side error classification unreliable AI Coding Tools Claude Code Updated May 21, 2026
Fix Figma MCP OAuth flow completing but MCP server disconnecting and reconnecting with only auth placeholder tools instead of full Figma toolset Includes evidence for Claude Code troubleshooting demand.
Figma MCP gets stuck in authenticate-only tools after successful OAuth, never exposing real tools like get_file or get_comments AI Coding Tools Claude Code Updated May 21, 2026
Fix Claude Code failing to persist OAuth tokens for Greptile MCP plugin despite successful OAuth flow, leaving plugin unusable Includes evidence for Claude Code troubleshooting demand.
OAuth flow completes (code consumed by localhost callback) but mcpOAuth credential map contains zero plugin:greptile entries, plugin permanently stuck in needs_auth state OpenAI API OpenAI API Updated May 21, 2026
Understand and unify rate limit error handling between OpenAI's Responses API and Chat Completions API so developers don't need separate error paths for each endpoint Includes evidence for OpenAI API troubleshooting demand.
Responses API and Chat Completions API handle rate limit errors differently (different error codes, headers, or body formats), breaking unified error handling LiteLLM LiteLLM Updated May 21, 2026
Improve LiteLLM proxy error propagation so timeout, auth, and rate-limit failures from upstream models are surfaced with correct error codes to callers Includes evidence for LiteLLM troubleshooting demand.
LiteLLM proxy routes requests to upstream models but fails to propagate error details when upstream timeout/auth failures occur, returning generic proxy errors Anthropic API Anthropic API Updated May 21, 2026
Fix incorrect HTTP status returned when Anthropic API SSE stream breaks mid-response, causing client-side parsing failures Includes evidence for Anthropic API troubleshooting demand.
SSE stream error returns HTTP 200 instead of actual error code during mid-stream interruption AI Coding Tools Claude Code Updated May 21, 2026
Fix Opus 4.7 model returning unparseable tool call responses in Claude Code, blocking all agent operations Includes evidence for Claude Code troubleshooting demand.
