UiPath LangChain Client [langchain-v1.14.1]

[1.14.1] - 2026-06-23

Fixed

• WrappedBotoClient (the httpx-backed Bedrock shim) now calls raise_for_status() in converse, invoke_model, and the streaming generator before reading the response. Previously a non-2xx gateway response (e.g. 403 License-not-available) was parsed as a normal result and handed to langchain_aws, which raised a misleading ValueError("No 'output' key found in the response from the Bedrock Converse API ... misconfiguration of endpoint or region") — the real status code and detail were lost. Gateway HTTP errors now surface as the patched UiPathAPIError subclass (e.g. UiPathPermissionDeniedError), matching the OpenAI and Vertex paths. For streaming responses the error body is read first so the typed exception retains its detail.
