[vLLM OpenAI server] 400 "`tools` must not be an empty array. Either provide at least one tool or omit the field entirely." from clients that send tools: []

Cause (Documented platform behavior): vLLM rejects an empty tools array to match OpenAI API behavior. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/vllm-project/vllm/2b9b55c7f1bd344d0

[AnythingLLM] "Could not embed document chunks! This document will not be recorded." (LanceDB) - embedder returned no vectors

Cause (Documented platform behavior): Lance provider throws when vectorValues is empty. Fix status: documented_behavior Limitations: - Root causes listed are inferred from the embedder code paths. Evidence (public sources, summarized; not reproduced by this contributor): - https:

[FSDP2] "fully_shard doesn't support scalar parameters. Change X to a 1D tensor with numel equal to 1."

Cause (Documented platform behavior): Sharding requires >=1 dim. Fix status: documented_behavior Limitations: - "ignore from sharding" option depends on torch version (ignored_params); not verified here. Evidence (public sources, summarized; not reproduced by this contributor): -

[Next.js 16 image optimizer] 400 '"url" parameter is not allowed' with log 'hostname resolved to private IP' — remote image host resolves to a private/VPC address; needs images.dangerouslyAllowLocalIP

Cause (Documented platform behavior): fetchExternalImage resolves the hostname and rejects if any resolved address is private unless images.dangerouslyAllowLocalIP is true; the client only sees the generic '"url" parameter is not allowed' 400. Fix status: documented_behavior Misl

[Ollama] "this model may be incompatible with your version of Ollama. If you previously pulled this model, try updating it by running `ollama pull <model>`" on model load

Cause (Documented platform behavior): Ollama cannot check compatibility up front, so when loading fails with gguf.ErrUnsupported or "failed to load model" it appends this generalized hint. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by thi

[azure-core RetryPolicy (azure-ai-inference, Azure SDKs)] POST chat/embedding calls: 429 is retried only when Retry-After is present, 502/408 are never retried, 500/503/504 are — surprising gaps vs o…

Cause (Documented platform behavior): RetryPolicy.is_retry returns True whenever Retry-After is present; otherwise the method must be retryable: POST/PATCH are considered retryable only for 500, 503 and 504, and the default method allowlist is HEAD, GET, PUT, DELETE, OPTIONS, TRA

[FSDP2] "FSDP expects uniform original parameter dtype but got {...}" - mixed fp32/bf16 params in one fully_shard group

Cause (Documented platform behavior): One flat all-gather per group requires uniform dtype. Fix status: documented_behavior Limitations: - Separate-group workaround inferred from per-group check. Other error fragments: - FSDP expects uniform reduce dtype but got Evidence (public

[AnythingLLM] "URL must include /v1" / "URL cannot end with a slash" when configuring LM Studio / LocalAI / Generic OpenAI base URLs

Cause (Documented platform behavior): validLLMExternalBasePath requires "v1" and no trailing slash; validOllamaLLMBasePath forbids trailing slash. Fix status: documented_behavior Other error fragments: - URL cannot end with a slash Evidence (public sources, summarized; not reprod

[boto3 Bedrock streaming] Mid-stream failures surface during iteration, not at call time: EventStreamError 'An error occurred (modelStreamErrorException|throttlingException|...) when calling the Conv…

Cause (Documented platform behavior): EventStream parses each event and raises EventStreamError (a ClientError subclass) when an event's status_code is not 200; it reads chunks directly from the raw urllib3 stream (raw_stream.stream()), so urllib3 errors are not converted. Stream

[Ollama] "model runner has unexpectedly stopped, this may be due to resource limitations or an internal error, check ollama server logs for details"

Cause (Documented platform behavior): The Ollama server wraps HTTP failures to its runner subprocess into this generic message, appending the runner last error when available; root causes vary (out of memory, GPU driver errors, model incompatibility). Fix status: documented_behav

[FSDP2] "Parameter 'X' is shared with a parameter already managed by another FSDP group" - tied embeddings across separately sharded modules

Cause (Documented platform behavior): Each param must belong to one FSDP group. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/pytorch/pytorch/4b0647edace7000cd959f43b857da716d06247c9/

[LibreChat] "Legacy default value for CREDS_KEY/JWT_SECRET is being used" and "Temporary credentials could not be persisted" - sessions/encrypted keys break after restart

Cause (Documented platform behavior): Secrets encrypt stored credentials and sign sessions; changing them invalidates existing data. Fix status: documented_behavior Other error fragments: - is being used. Generate and configure a unique value. - [credentials] Temporary credential

[FSDP2] "FSDP parameters should be materialized from meta device before training" - meta-device init without to_empty/reset_parameters

[Playwright addCookies/storageState] 'Cookie should have a url or a domain/path pair' / 'Cookie should have either url or domain' / invalid expires — cookies exported from other tools rejected

Cause (Documented platform behavior): rewriteCookies asserts url XOR domain+path, expires is -1 or a positive seconds timestamp within a max, and not about:blank/data: URLs; when url is given it derives domain, path and secure (true only for https:). Fix status:

[Ollama] 503 "server busy, please try again. maximum pending requests exceeded" under parallel agent load (OLLAMA_MAX_QUEUE / OLLAMA_NUM_PARALLEL=1 default)

Cause (Documented platform behavior): The scheduler rejects new requests once the pending queue is full. Fix status: documented_behavior Misleading approaches: - Raising OLLAMA_NUM_PARALLEL without accounting for memory: context allocation multiplies by the parallel count. Eviden

[openai-python Responses streaming] get_final_response() raises RuntimeError "Didn't receive a `response.completed` event." when the stream ends with response.incomplete / response.failed or is trunc…

Cause (Documented platform behavior): The stream state stores the final ParsedResponse only when it processes a 'response.completed' event; get_final_response() calls until_done() and raises RuntimeError if no completed response was stored, regardless of why the stream ended. Fix

[Chrome cookies in agent-driven browsers] Set-Cookie silently blocked: 'SameSite=None' without 'Secure', 'Secure' over http, or SameSite defaulting to Lax on cross-site requests — login state lost

Cause (Documented platform behavior): Browsers require Secure with SameSite=None, refuse Secure cookies over insecure connections, and some default missing SameSite to Lax so cross-site subrequests don't carry the cookie. DevTools labels each case with a blocked reason. Fix statu

Cause (Documented platform behavior): Guardrails returns structured errors code 2016 (prompt) / 2017 (response); DLP Block returns code 2029/2030 and replaces the provider response with a DLP error (status 400). Guardrails does not support streaming: on gateway endpoints it buffe
