/**
 * The `RemoteGraph` class is a client implementation for calling remote
 * APIs that implement the LangGraph Server API specification.
 *
 * For example, the `RemoteGraph` class can be used to call APIs from deployments
 * on LangGraph Cloud.
 *
 * `RemoteGraph` behaves the same way as a `StateGraph` and can be used directly as
 * a node in another `StateGraph`.
 *
 * @example
 * ```ts
 * import { RemoteGraph } from "@langchain/langgraph/remote";
 *
 * // Can also pass a LangGraph SDK client instance directly
 * const remoteGraph = new RemoteGraph({
 *   graphId: process.env.LANGGRAPH_REMOTE_GRAPH_ID!,
 *   apiKey: process.env.LANGGRAPH_REMOTE_GRAPH_API_KEY,
 *   url: process.env.LANGGRAPH_REMOTE_GRAPH_API_URL,
 * });
 *
 * const input = {
 *   messages: [
 *     {
 *       role: "human",
 *       content: "Hello world!",
 *     },
 *   ],
 * };
 *
 * const config = {
 *   configurable: { thread_id: "threadId1" },
 * };
 *
 * await remoteGraph.invoke(input, config);
 * ```
