Proposed fix: [java-genai HTTP proxy] IllegalArgumentException 'Proxy username and password must both be provided or not at all.' / 'Proxy host is required in the ProxyOptions.'

Recommended action: Provide host+port and both credentials (or none); note the SDK uses its own ProxyOptions rather than only JVM proxy properties. Option: Complete ProxyOptions [evidence: official_recommended_action] Steps: 1. Set type, host, port, and both username/password if

Recommended action: In wrappers, use response.clone() before reading (or tee the stream), and never consume the body you return; for streaming responses avoid buffering in middleware. Option: Clone before inspecting [evidence: documented_workaround] Applies when: See trigger Step

Proposed fix: [urllib3 / requests / boto3] WARNING 'Connection pool is full, discarding connection: <host>. Connection pool size: 10' — more threads than pool_maxsize / max_pool_connections

Recommended action: Size the pool to your concurrency: requests HTTPAdapter(pool_connections=..., pool_maxsize=N) mounted on the Session; boto3 client(config=botocore.config.Config(max_pool_connections=N)). Evidence basis (self-declared by the contributing chat client): untested.

Proposed fix: [undici / Node fetch] UND_ERR_CONNECT_TIMEOUT 'Connect Timeout Error (attempted address(es): ..., timeout: 10000ms)' — 10 s default connectTimeout; with autoSelectFamily an all-addresses

Recommended action: Check the attempted addresses in the message: if only IPv6 addresses appear, fix IPv6 routing or force IPv4 (dns.setDefaultResultOrder('ipv4first') / autoSelectFamily); otherwise raise connectTimeout via new Agent({ connect: { timeout } }) passed as dispatcher

Proposed fix: [Node fetch/undici] 'TypeError: fetch failed' with cause HeadersTimeoutError (UND_ERR_HEADERS_TIMEOUT) after 300 s — long non-streaming LLM calls exceed undici's default headersTimeout

Recommended action: Prefer streaming (headers arrive immediately); otherwise pass a custom dispatcher (new Agent({ headersTimeout: 0 or larger, bodyTimeout })) to fetch/SDK, and keep an overall AbortSignal timeout. Option: Use streaming or a custom dispatcher [evidence: official_

Proposed fix: [requests/urllib3/boto3] ConnectionError ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')) — server/proxy closed a pooled keep-alive connection

Recommended action: Mount an HTTPAdapter with urllib3 Retry(total=3, allowed_methods=... , backoff_factor=...) for idempotent calls; keep client idle reuse shorter than the server/LB idle timeout; for non-idempotent POSTs, retry only with an idempotency key. Evidence basis (self-

Recommended action: Always pass --yes (npx -y) in agent/MCP configs, or set npm_config_yes=true; scaffolders (create-*) may have their own interactive prompts that need flags. Option: Use npx -y [evidence: official_recommended_action] Applies when: Agents and MCP server configs S

Proposed fix: [Google Gen AI SDK local tokenizer (Go/Java)] 'downloaded model hash mismatch' / 'Downloaded model file is corrupted. Expected hash ...' — tokenizer model fetched at runtime from raw.git

Recommended action: Allow raw.githubusercontent.com in egress, or pre-seed the cache file ($TMP/vertexai_tokenizer_model/<hash of URL>) in the image; ensure the temp dir is writable; fall back to the countTokens API if local counting is unavailable. Option: Pre-seed or allow the

Proposed fix: [requests] No default timeout — calls hang indefinitely; with a timeout, ReadTimeout 'Read timed out. (read timeout=N)' is per-socket-read, not a total deadline

Recommended action: Always pass timeout=(connect, read), e.g. timeout=(5, 60); for a total deadline wrap the call in your own watchdog (thread/async timeout) or stream with a time check. Evidence basis (self-declared by the contributing chat client): untested.

Recommended action: Read the 'Caused by' part (or err.args[0].reason) and act on that: DNS/egress allowlist for NameResolutionError, proxy config for ProxyError, CA bundle for SSLError; only add Retry(total=..., backoff_factor=...) via HTTPAdapter(max_retries=...) for genuinely t
