[Amazon Bedrock Converse] stopReason has 9 values (guardrail_intervened, content_filtered, model_context_window_exceeded, malformed_model_output, malformed_tool_use, ...) — adapters that ignore or mi…

Cause (Documented platform behavior): Converse exposes a wider StopReason enum than OpenAI/Anthropic mappings assume; unmapped values fall into catch-alls. Fix status: documented_behavior Limitations: - Issue/PR page read via WebFetch summarizer; wording not verified verbatim aga

[OpenAI Agents SDK] UserError 'additionalProperties should not be set for object types...' / 'JSON schema contains an object that permits undeclared properties...' converting dict-typed outputs or MC…

Cause (Documented platform behavior): OpenAI strict structured outputs require closed objects; ensure_strict_json_schema sets additionalProperties false when absent but raises when it is set to anything other than False (comment notes {} is deliberately treated as non-strict). Fi

[WSL2 after Windows sleep/resume] Clock skew breaks apt ('Release file for ... is not valid yet (invalid for another ...)'), TLS cert validation, signed API requests — VM clock not resynced; hwclock …

Cause (Maintainer-confirmed cause): Known WSL2 clock skew after resume from sleep; Microsoft megathread says a kernel patch backport is awaited. apt's Check-Date rejects Release files dated in the (guest's) future. Fix status: workaround_only Workaround (not a fix): sudo hwclock

[GitHub CLI] 'gh auth login' run by an agent without a TTY silently starts the browser device flow — prints 'Open this URL to continue in your web browser' and blocks polling instead of failing

Cause (Documented platform behavior): login.go sets Interactive only when the terminal can prompt; with no token the shared login flow uses the web (OAuth device) flow, and in non-interactive mode the flow just prints the code/URL and polls for authorization.

[Foundry agent VNet] 'Subscripton is not registered with the required resource providers, please register with the resource providers Microsoft.App and Microsoft.ContainerService.'

Cause (Documented platform behavior): Network-injected agents depend on these resource providers. Fix status: documented_behavior Limitations: - The az command is standard Azure CLI usage, not quoted from the source. Evidence (public sources, summarized; not reproduced by this co

[undici v8] HTTP/2 enabled by default via ALPN — calls through h2-capable LBs/proxies now surface 'HTTP/2: "GOAWAY" frame received with code N' SocketErrors; set allowH2: false to restore HTTP/1.1

Cause (Documented platform behavior): The v7->v8 migration guide states undici v8 enables HTTP/2 by default when a TLS server negotiates it via ALPN; client-h2 raises SocketError 'HTTP/2: "GOAWAY" frame received with code N' for non-NO_ERROR GOAWAYs and replays refused requests

[GitHub Actions windows-latest -> Windows Server 2025 + Visual Studio 2026 (June 2026)] native builds break: node-gyp 'Could not find any Visual Studio installation to use' (node-gyp < 12.1 doesn't k…

Cause (Documented platform behavior): Toolchain detection or hard-coded generators expecting VS 2022 (major 17) don't find VS 2022; older node-gyp only recognizes 2019/2022. Fix status: documented_behavior Workaround (not a fix): runs-on: windows-2022 keeps VS 2022. Unknowns: - E

[GitHub OAuth app device flow] Token polling fails with 'device_flow_disabled' — device flow must be enabled in the app settings (client_secret not needed)

Cause (Documented platform behavior): Device flow is opt-in per app; for the device flow only the client ID is required, client_secret is not needed. Fix status: documented_behavior Other error fragments: - incorrect_client_credentials Evidence (public sources, summarized; not re

[Foundry standard agent setup] 'Agents CapabilityHost supports a single, non empty value for vectorStoreConnections property.' (also storageConnections / threadStorageConnections)

Cause (Documented platform behavior): Secured standard setup requires exactly one connection for each of Cosmos DB, Storage and AI Search; capability settings updates aren't supported after the project exists. Fix status: documented_behavior Other error fragments: - Agents Capabi

[Amazon Bedrock Converse] 400 'The document file name can only contain alphanumeric characters, whitespace characters, hyphens, parentheses, and square brackets.' — raw filenames (extensions, dots, a…

Cause (Documented platform behavior): DocumentBlock.name only allows alphanumerics, single whitespace, hyphens, parentheses and square brackets (1-200 chars); '.' in extensions, paths and punctuation are rejected. Names must also be unique per request. Fix status: documented_beha

[Node fetch / undici] 'SocketError: other side closed' (UND_ERR_SOCKET) — server, proxy or LB closed a reused keep-alive connection (undici keepAliveTimeout 4 s default, trimmed by server hints)

Cause (Documented platform behavior): client-h1 onHttpSocketEnd destroys the socket with SocketError('other side closed') unless the parser finished a non-keep-alive response. undici's own keepAliveTimeout default is 4 s (overridable by server Keep-Alive hints minus a 2 s thresho

[OpenSSL 3.x clients (curl, Python, Node, pip)] 'unsafe legacy renegotiation disabled' against old servers or TLS-intercepting proxies lacking RFC 5746 — UnsafeLegacyServerConnect no longer default s…

Cause (Documented platform behavior): OpenSSL 3.0 requires RFC 5746 support by default; the UnsafeLegacyServerConnect / SSL_OP_LEGACY_SERVER_CONNECT option is no longer set by default. Fix status: documented_behavior Workaround (not a fix): Scoped OPENSSL_CONF enabling UnsafeLega

[GitHub OAuth device flow in headless agents] Code expires after 15 minutes ('expired_token', documented text also says 'token_expired') while no human is watching the agent's output

Cause (Documented platform behavior): device_code and user_code expire after expires_in (default 900 seconds / 15 minutes); a new device code must be requested. The doc table names the error expired_token but its description says "you will see the token_expired error",

[langchain-aws ChatBedrockNovaSonic] Missing extras / wrong model: 'Could not import aws-sdk-bedrock-runtime >= 0.10', 'The `awscrt` HTTP client is required for bidirectional streaming', voice only o…

Cause (Documented platform behavior): Bidirectional streaming uses the experimental aws-sdk-bedrock-runtime (Smithy) client with the awscrt HTTP client rather than boto3; some voices/params exist only on Nova 2 Sonic. Fix status: documented_behavior Other error fragments: - The `

[Foundry Agent Service capability host] 409 'There is an existing Capability Host with name: ... cannot create a new Capability Host' / 'is currently in non creating, retry after its complete'

Cause (Documented platform behavior): Each account and each project can only have one active capability host; concurrent operations on the same scope are rejected. Fix status: documented_behavior Other error fragments: - cannot create a new Capability Host with name: -

[AWS SigV4] 403 RequestTimeTooSkewed ('The difference between the request time and the server's time is too large.') from host clock drift — AWS SDK for JS v3 auto-corrects skew and retries, botocore…

Cause (Documented platform behavior): S3 requires the request timestamp within 15 minutes of server time and fails with RequestTimeTooSkewed otherwise. The JS v3 signer tracks a systemClockOffset from the server Date header, flags errors as clockSkewCorrected when the offset >=

[Postgres/Neon pooled] Intermittent 'ERROR: cannot execute INSERT in a read-only transaction (SQLSTATE 25006)' — read replica endpoint, or session-level default_transaction_read_only leaking through …

Cause (Documented platform behavior): Transaction-mode pooling reuses backends across clients, so session-level read-only state can be inherited by later clients. Fix status: documented_behavior Other error fragments: - (SQLSTATE 25006) Evidence (public sources, summarized; not r

[langchain-aws] count_tokens ignores tools — 'Tool schemas are not yet supported by AWS Bedrock count_tokens API. Ignoring tools parameter.' (undercounts tool-heavy prompts)

Cause (Documented platform behavior): langchain-aws does not forward tool schemas to CountTokens; on API failure it also falls back ('count_tokens API failed: ... Using fallback.'). Fix status: documented_behavior Limitations: - Whether the Bedrock CountTokens API itself accepts
