keeps defaulting auth to Anthropic Console API billing account instead of claude.ai Max subscription; costs hundreds of dollars in unexpected API spend Fix code 10375 error preventing Cloudflare Worker deployments that combine Durable Objects with remote bindings (KV/D1/R2/AI) Includes evidence for Cloudflare troubleshooting demand.
wrangler upload rejected with code 10375 'Durable Object bindings cannot be used with edge preview' after removal of wrangler dev --remote on 2026-05-18 Fix regression in Next.js 16.2.6+ where not-found.tsx fails with FUNCTION_INVOCATION_FAILED in production when cacheComponents is enabled Includes evidence for Vercel troubleshooting demand.

Cannot find module 'require-in-the-middle-<hash>' failed to load external module in instrumentation hook on Vercel prebuilt deployment (Next.js 16.2.6 + Turbopack + pnpm) Debug why wrangler deploy appears to succeed but doesn't actually deploy in CI environment; fix silent failure behavior Includes evidence for Cloudflare troubleshooting demand.
wrangler deploy exits without error message, output, or exit code indication — silent failure in Woodpecker CI (wrangler 4.90.1, bun, linux/docker) Fix 400 error caused by invalid Unicode surrogate pair in large JSON request body sent to Anthropic/Claude API Includes evidence for Claude Code troubleshooting demand.
API Error: 400 The request body is not valid JSON: no low surrogate in string: line 1 column 195621 (char 195620) Fix OAuth token exchange failure when Claude Code connects to remote MCP server behind Cloudflare Access SaaS Includes evidence for Claude Code troubleshooting demand.
OAuth Token Exchange not completed in 2.1.143 with non-DCR AS (Cloudflare Access for SaaS) Fix claude plugin install corrupting .claude.json config and losing subscription state, triggering endless OAuth prompts Includes evidence for Claude Code troubleshooting demand.
claude plugin install silently strips fields from .claude.json (~75 KB → ~1.5 KB), dropping oauthAccount.organizationType and forcing re-OAuth Fix OpenAI images/edit endpoint 400 error when trying to pass URL-based image input as documented Includes evidence for OpenAI API troubleshooting demand.
client.images.edit() API throws 400 error when passing image_url as input instead of file object Fix production deployment failure on Vercel caused by Turbopack alias resolution breaking in prebuilt mode with pnpm + symlinks Includes evidence for Vercel troubleshooting demand.
Next.js 16 Turbopack hashed server external aliases can become unresolved in Vercel prebuilt deployments with pnpm MCP server launches but dies before responding. Developer needs to diagnose why child process exits (missing binary, Node.js init completes with no event-loop work, npx path issues on Windows). Includes evidence for Claude Code troubleshooting demand.
Connection closed (Picking well-maintained servers avoids a lot of this...) — MCP stdio process died between connect and first tools/list response Developer running long autonomous Claude Code sessions hits sudden 401 auth failures; needs recovery procedure (/logout then /login, cache clearing, fresh token lifecycle management). Includes evidence for Claude Code troubleshooting demand.
authentication_error (401) — OAuth token expired mid-autonomous run, every subsequent tool call returns auth error until re-login Developer configures an MCP server for Claude Code but it immediately fails with -32000; needs systematic troubleshooting steps (command isolation, env vars, stdout pollution, Node.js event loop). Includes evidence for Claude Code troubleshooting demand.
Connection closed / MCP server <name>: error -32000 — generic JSON-RPC server error indicating MCP subprocess crashed during init Developer paying for Copilot Pro+ hits an unexpectedly long rate-limit block that breaks coding workflow for hours; needs workaround or faster resolution path. Includes evidence for GitHub Copilot troubleshooting demand.
weekly rate limit exceeded — Copilot locked out for 44 hours after hitting rate limits; sub-30s retry windows cycle indefinitely Handle OpenAI API background response failures with proper error codes so applications can catch and retry specific error types reliably Includes evidence for OpenAI API troubleshooting demand.
Background responses failures lack a stable code/name that maps to an exception class — API errors cannot be programmatically caught Resolve spurious usage limit error messages on Claude Code Max plan when user hasn't actually hit their rate or usage limits Includes evidence for Claude Code troubleshooting demand.
