Proposed fix: [OpenAI Agents JS] Responses WebSocket transport: 'connection closed before any response events were received. The feature may not be enabled for this account or model yet.'

Recommended action: Fall back to the default HTTP Responses transport; confirm model/account support for the websocket mode; handle the reused-connection case with application-level idempotency before retrying. Option: Switch to the HTTP Responses transport [evidence: official_re

Proposed fix: [Claude Code Windows install] 'Failed to download binary: The process cannot access the file ... because it is being used by another process'

Recommended action: Close other installer windows, wait for AV scan, delete %USERPROFILE%\.claude\downloads, rerun installer. Option: Clear downloads and rerun [evidence: official_recommended_action] Applies when: see problem Steps: 1. Remove-Item -Recurse -Force "$env:USERPROFIL

Proposed fix: [Docker/WSL on Windows checkouts] '/bin/bash^M: bad interpreter' or misleading 'exec /usr/local/bin/entrypoint.sh: no such file or directory' — CRLF shebang from core.autocrlf

Recommended action: Force LF for shell scripts via .gitattributes ('*.sh text eol=lf'), run 'git add --renormalize .', commit, and rebuild the image. Option: Pin LF for scripts with .gitattributes and renormalize [evidence: official_recommended_action] Applies when: Any repo whos

Proposed fix: [macOS agents] osascript fails 'Not authorized to send Apple events to Terminal. (-1743)' — TCC Automation denied silently for the responsible app

Recommended action: Add NSAppleEventsUsageDescription to the launching app's Info.plist so macOS prompts; grant in System Settings > Privacy & Security > Automation; if mapping is broken reinstall the host app properly (tccutil reset AppleEvents alone may not help). Option: Make

Proposed fix: [npm] 'npm ERR! code EINTEGRITY ... integrity checksum failed when using sha512: wanted sha512-... but got sha512-...' — downloaded tarball differs from the lockfile/registry integrity (

Recommended action: Identify which package/registry: compare the lockfile 'resolved' URL and 'integrity' with what the configured registry serves; regenerate the lockfile entry against the registry CI actually uses (or align the registry config) and investigate unexpected tarball

Proposed fix: [Claude Code via LLM gateway / Bedrock / Vertex] 'API Error: 400 ... Unexpected value(s) `<beta>` for the `anthropic-beta` header' or '... Extra inputs are not permitted ... context_mana

Recommended action: Configure the gateway to forward anthropic-beta (feature pass-through); otherwise set CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1 before launching. Option: Forward anthropic-beta or disable experimental betas [evidence: official_recommended_action] Applies when:

Proposed fix: [OpenAI Python structured outputs] TypeError 'Non BaseModel types are only supported with Pydantic v2' when passing TypedDict/dataclass/list types

Recommended action: Upgrade to pydantic>=2 (check pip show pydantic / dependency pins), or wrap the type in a BaseModel subclass. Option: Use Pydantic v2 or a BaseModel [evidence: documented_workaround] Steps: 1. pip install -U 'pydantic>=2' 2. or class Out(BaseModel): items:

Proposed fix: [@actions/cache >=6.1] Cache not saved/restored with warning 'cache write denied:' / 'cache read denied:' — run's cache token downgraded to read-only (untrusted trigger) or ACTIONS_CACHE

Recommended action: Treat as policy, not a bug: check repository cache policy for untrusted events and ACTIONS_CACHE_MODE; populate caches from trusted runs (e.g. default-branch pushes) so untrusted runs can restore. Option: Seed caches from trusted runs [evidence: documented_wor

Proposed fix: [Modal Sandboxes] Agent sandbox dies after 5 minutes with modal.exception.SandboxTimeoutError (default timeout=300 s lifetime), or is killed by sandbox.terminate() used to cancel one com

Recommended action: Pass an explicit timeout sized to the agent session (and idle_timeout if desired) at Sandbox.create; cancel individual commands by killing the process inside the sandbox rather than terminating the sandbox; check liveness before reuse and recreate/snapshot as

Proposed fix: [actions/cache] 'Failed to save: Unable to reserve cache with key X, another job may be creating this cache.' — usually the key already exists (caches are immutable), so updated deps are

Recommended action: If you need to refresh the cache, use a key unique per run (e.g. include github.run_id) with restore-keys for the nearest match; otherwise ignore the warning when the key legitimately exists. Keep in mind the 10GB per-repo limit

Proposed fix: [E2B SDK] commands.run() times out after 60 s by default ('deadline_exceeded') vs 'Request timed out — the 'request_timeout' option can be used...' — three different timeouts

Recommended action: Pass timeout=0 (or larger) to commands.run for long commands, or run in background and poll; raise request_timeout for slow API calls; inspect TimeoutException type to tell which fired. Option: Raise command timeout [evidence: official_recommended_action] Appl

Proposed fix: [openai-node] 'ResponsesWS from "openai/resources/responses/ws" requires the "ws" package but it could not be loaded.' (ws is an optional peer dependency)

Recommended action: npm install ws (and @types/ws for TS); ensure bundlers keep it as an external/runtime dependency; in browsers use the native WebSocket variants. Option: Install ws [evidence: official_recommended_action] Applies when: OpenAI Node/TypeScript SDK (openai) / Resp
