[Anthropic Bedrock/AWS SDKs] Partial static AWS keys rejected — TS '`awsAccessKey` and `awsSecretAccessKey` must be provided together. You provided only one.' / Python '`<x>` was provided without `<y…

Cause (Documented platform behavior): SDKs refuse to mix a partial static credential with the default chain. Fix status: documented_behavior Limitations: - Read from the published npm tarball (bundled JS); not executed. Other error fragments: - Both must be provided together,

[Puppeteer / @puppeteer/browsers] Chrome for Testing on linux-arm64: downloadable only from @puppeteer/browsers 3.2.0 and Chrome builds >= 153.0.8001.0; unsupported OSes throw 'Cannot download a bina…

Cause (Documented platform behavior): detectBrowserPlatform maps linux+arm64 to LINUX_ARM, but the CfT folder is 'linux-arm64' only for buildId >= 153.0.8001.0 (earlier builds map to 'linux64'); platforms outside darwin/linux/win32 return undefined and the installer throws. Fix s

[LLM provider Python SDKs] Timeout exception comparison: openai 'Request timed out.', anthropic 'Request timed out or interrupted...', botocore 'Read timeout on endpoint URL', azure ServiceResponseTi…

Cause (Documented platform behavior): Each SDK wraps (or does not wrap) its transport's timeout differently. openai/anthropic catch httpx2 TimeoutException and raise APITimeoutError (a subclass of APIConnectionError) after retries; defaults are 600 s total / 5 s connect. botocore

[Amazon Nova 2 on Bedrock] reasoningConfig needs maxReasoningEffort low|medium|high — 'When reasoningConfig type is 'enabled', 'maxReasoningEffort' must be specified' (Anthropic thinking/budget_token…

Cause (Documented platform behavior): Nova 2 uses its own reasoningConfig {type:'enabled', maxReasoningEffort} in additionalModelRequestFields. Fix status: documented_behavior Limitations: - Validation shown is client-side (langchain-aws, LiteLLM); server error text not captured.

[Foundry Azure AI Search tool] 'Unable to connect to Azure AI Search Resource ... [DNS server returned answer with no data]' with key-based connection in a private network

Cause (Documented platform behavior): Key-based authentication isn't supported with private virtual networking for the AI Search tool. Fix status: documented_behavior Misleading approaches: - Debugging DNS/private endpoints first; the documented cause is the auth type. Other erro

problem · Revision 1

[Playwright remote browsers (connect / cloud browser services)] download.path() throws 'Path is not available when connecting remotely'; localhost app unreachable unless exposeNetwork is set

Cause (Documented platform behavior): Downloaded file lives on the remote browser host, so path() is unavailable (documented: 'The method throws when connected remotely'); the remote browser's localhost is not the client's localhost unless exposeNetwork forwards it. Fix status: d

[Amazon Bedrock Converse] requestMetadata rejected — max 16 entries, keys 1-256 / values 0-256 chars from [a-zA-Z0-9\s:_@$#=/+,.-] (LiteLLM: 'requestMetadata key ... contains invalid characters')

Cause (Documented platform behavior): Converse RequestMetadata map is constrained (max 16; key/value patterns) for invocation-log filtering. Fix status: documented_behavior Limitations: - LiteLLM validates client-side; the raw Bedrock error text for violations is not captured her

[nginx in front of LLM backends] Non-streaming or slow-first-token requests fail with 504 after 60 s — proxy_read_timeout default 60s ('upstream timed out')

Cause (Documented platform behavior): proxy_read_timeout is measured between two successive read operations, not for the whole response; if the proxied server sends nothing within it, nginx closes the connection. Fix status: documented_behavior Limitations: - exact string is gene

[Foundry Grounding with Bing Custom Search] Tool_User_Error '[bing_search] Failed to call Get Custom Search Instance with status 404' — 'Instance or Customer not found'

Cause (Documented platform behavior): The configured custom search instance cannot be found in the connected resource. Fix status: documented_behavior Other error fragments: - Instance or Customer not found - Tool_User_Error Evidence (public sources, summarized; not reproduced by

[Playwright Test] 'http://localhost:PORT is already used, make sure that nothing is running on the port/url or set reuseExistingServer:true in config.webServer.' — leftover dev server from a previous…

Cause (Documented platform behavior): With reuseExistingServer false, the plugin throws if the url/port already responds; if the command exits, it reports the exit code. Fix status: documented_behavior Other error fragments: - Process from config.webServer was not able to start.

[OpenSSL / Python ssl / Node TLS] 'certificate is not yet valid' (CERT_NOT_YET_VALID) or 'certificate has expired' against valid LLM API certs — host clock is wrong (newer OpenSSL says 'or the system…

Cause (Documented platform behavior): OpenSSL's X509_V_ERR_CERT_NOT_YET_VALID/CERT_HAS_EXPIRED verification errors; OpenSSL master reworded the not-yet-valid text to mention an incorrect system clock (3.5.0 still says 'certificate is not yet valid'). Node exposes the same conditi

[nginx reverse proxy] 413 Request Entity Too Large for file/base64-image uploads over 1 MB — default client_max_body_size is 1m (error log: 'client intended to send too large body')

Cause (Documented platform behavior): nginx rejects bodies above client_max_body_size with 413 and logs "client intended to send too large body: N bytes"; size 0 disables the check. Fix status: documented_behavior Misleading approaches: - Increasing the application framework limi

[Playwright Test] 'Error: Timed out waiting 60000ms from config.webServer.' in CI — server bound to IPv4/IPv6 differently from the probed URL, or slow build inside command

Cause (Documented platform behavior): Readiness probe never succeeds: with Node 17+ 'localhost' may resolve to ::1 first while the server listens on IPv4 (reported in #20784); or startup legitimately exceeds webServer.timeout (default 60000 ms). Also the url must return 2xx/3xx/4

[Standard Webhooks libs] 'Message timestamp too old' / 'Message timestamp too new' — fixed 5-minute tolerance rejects queued/replayed deliveries and clock-skewed hosts

Cause (Documented platform behavior): The libraries hard-code a 5 minute tolerance for replay protection; the timestamp is part of the signed content, so it cannot be edited. Fix status: documented_behavior Other error fragments: - Message timestamp too new - Invalid

[Strands Agents Bedrock Mantle config] 'Unknown Bedrock endpoint ... Use 'bedrock-mantle' or 'bedrock-runtime'', 'Could not resolve an AWS region for Amazon Bedrock', and missing 'aws-bedrock-token-g…

Cause (Documented platform behavior): Mantle auth mints short-term Bedrock API keys (bearer tokens) from AWS credentials via aws-bedrock-token-generator; endpoints and regions must be explicit. Fix status: documented_behavior Limitations: - Short-term keys are capped at 12h lifet
