Fix MCP tools in Claude Code returning user denied error even when permissions.allow contains correct server entry, no permission prompt appears Includes evidence for Claude Code troubleshooting demand.
tools spuriously rejected as 'user denied' without permission prompt Fix Claude Code Chrome MCP tools failing on all domains when navigating or reading pages Includes evidence for Claude Code troubleshooting demand.
"Navigation to this domain is not allowed" / "Permission denied for reading pages on this domain" Implement fair queuing in LiteLLM proxy to prevent single client from monopolizing model capacity and causing starvation for other tenants Includes evidence for LiteLLM troubleshooting demand.
No fair queuing — traffic burst from one client starves other clients' requests Fix Vercel deployment build failure caused by exceeding the limit of 12 Serverless Functions per deployment Includes evidence for Vercel troubleshooting demand.
No more than 12 Serverless Functions can be added to a Deployment Fix Vercel deployment build failure due to out of memory during build step Includes evidence for Vercel troubleshooting demand.
build exited with code 1 (OOM during Vite/vanilla-extract build bundle) Fix Claude Code on Windows where git worktree remove fails with Permission denied because MCP servers aren't shut down before worktree operations Includes evidence for Claude Code troubleshooting demand.
worktree removal fails with Permission denied due to MCP shutdown ordering Developer using Anthropic streaming API loses connection mid-stream (TransportError) and can't catch it with standard except anthropic.APIConnectionError blocks — must know to also catch httpx.TransportError Includes evidence for Anthropic API troubleshooting demand.
Mid-stream httpx.TransportError leaks through as bare httpx exceptions because SSE body iteration has no try/except — customers standard retry ladder misses mid-stream drops User ran /login in Claude Code on Windows, sees success message but tool remains unauthenticated and rejects all commands afterward Includes evidence for Claude Code troubleshooting demand.
/login shows "Login successful" but immediately reverts to "Not logged in". Any subsequent command fails with "Not logged in". User upgraded to Docker 29.5.0 and rootless mode stopped working — docker socket file disappears, can't run any docker commands Includes evidence for Docker troubleshooting demand.
failed to connect to the docker API at unix:///run/user/1000/docker.sock; check if the path is correct and if the daemon is running: dial unix /run/user/1000/docker.sock: connect: no such file or directory Developer calls langgraph.with_structured_output() expecting it to preserve pre-bound tools, but they are silently dropped — functional regression breaking LLM function calling workflows Includes evidence for LangChain troubleshooting demand.
[langchain-openai] with_structured_output() silently drops previously bound tools and lacks support for OpenAI native tool bindings Developer using LiteLLM proxy finds that restricted users can see full model list via GET /v1/models endpoint despite access group restrictions, creating a security/authorization inconsistency Includes evidence for LiteLLM troubleshooting demand.
GET /v1/models ignores user.models restriction — shows all proxy models regardless of user access groups Developer using client.responses.create(background=True) cannot handle failure cases programmatically because the SDK returns 200 with failed payload instead of raising a typed exception Includes evidence for OpenAI API troubleshooting demand.
Background responses failures lack a stable code/name that maps to an exception class — HTTP poll returns 200 OK with status=failed but no typed exception is raised Fix ESM action crashes after @actions/glob v0.7.0 upgrade — broken import of Minimatch named export Includes evidence for GitHub Actions troubleshooting demand.
SyntaxError: The requested module 'minimatch' does not provide an export named 'Minimatch' (in @actions/glob v0.7.0) Fix Claude Code MCP server authentication returning HTTP 431 error on Linux platform Includes evidence for Claude Code troubleshooting demand.
HTTP ERROR 431 — MCP server authentication failure (browser restart!) Fix Docker rootless mode broken after upgrading to 29.5.0 — docker.sock missing Includes evidence for Docker troubleshooting demand.
failed to connect to the docker API at unix:///run/user/1000/docker.sock: dial unix /run/user/1000/docker.sock: connect: no such file or directory Fix OpenAI Batch API 404 error when using GPT-5 mini or nano models with chat completions endpoint Includes evidence for OpenAI API troubleshooting demand.
The model gpt-5-mini-2025-08-07-batch does not exist or you do not have access (HTTP 404 on /v1/chat/completions batch endpoint) Fix or work around Anthropic API rejecting valid but complex JSON schemas for structured outputs Includes evidence for Anthropic API troubleshooting demand.
400 invalid_request_error: "The compiled grammar is too large, which would cause performance issues" Fix OpenAI Python SDK failing to surface a typed exception for failed background Runs, preventing correct retry/backoff handling Includes evidence for OpenAI API troubleshooting demand.
status='failed', error.code='server_error' with HTTP 200 OK — no mapped SDK exception raised Fix AWS Bedrock SSE error events being swallowed with 200 status, making errors undetectable Includes evidence for Anthropic API troubleshooting demand.
SSE stream produces server-side errors but HTTP status_code stays 200 — errors invisible to caller Handle Anthropic Bedrock server-side errors (5xx/4xx responses) during streaming properly; understand transient error retry behavior and HTTP status exception handling Includes evidence for Anthropic API troubleshooting demand.
non-200 stream events raise ValueError instead of APIStatusError
