functionagent_error_typeBest-effort error-type name for an exception from RemoteAgent.astream. The LangGraph server serializes non-allowlisted exceptions as {"error": , "message": ...} wrapped in RemoteException(payload) (see langgraph_api.serde). The server-reported "error" type is the authoritative name when present; otherwise the exception's own class name is used. This is the single source of truth for "what error did the stream report" — both format_agent_exception (display string) and the UI's error-enrichment path (error-type dispatch) read it.https://reference.langchain.com/python/deepagents-code/remote_client/agent_error_type
functionformat_agent_exceptionRender an exception from RemoteAgent.astream for the UI. The LangGraph server serializes non-allowlisted exceptions as {"error": , "message": } (see langgraph_api.serde). RemoteGraph wraps that dict in RemoteException(payload), so the default str(exc) renders as an ugly Python dict repr in the UI.https://reference.langchain.com/python/deepagents-code/remote_client/format_agent_exception
classRemoteAgentClient that talks to a LangGraph server over HTTP+SSE. Wraps langgraph.pregel.remote.RemoteGraph which handles SSE parsing, stream-mode negotiation (messages-tuple), namespace extraction, and interrupt detection. This class adds streamed message-object conversion for the Textual adapter and thread-ID normalization. State snapshots are returned as provided by the server.https://reference.langchain.com/python/deepagents-code/remote_client/RemoteAgent
