When I use state management for the messages array it works, but when I'm trying to used them with an object doesn't works, actually I have my object like this:

const information = await bd.getInformation();
const GraphState = Annotation.Root({
    messages: Annotation<BaseMessage[]>({
      reducer: (x, y) => x.concat(y),
      default: () => [],
    }),
    userInfo: Annotation<UserInfo>({
      reducer: (x, y) => ({ ...x, ...y }),
      default: () => {
        console.log("SET INFO", information);
        return {
           name: information.name || "",
           age: information.age || 0,
        }
     },
    }),
});

The userInfo state is only used to read the default information, actually i don't want to update it, but the value that I ever get when I used on the node is the same:

SET INFO
{
name: "Bob",
age: 25
}

SUPERVISOR INFO
{
name: "user",
age: 0
}

This is an example about how I'm trying to use the state:

async function Supervisor(state: typeof GraphState.State) {
      const { messages, userInfo } = state;
      console.log("--- START SUPERVISOR ---");
      console.log("SUPERVISOR INFO", userInfo);

      const prompt = ChatPromptTemplate.fromTemplate(`... `);
      const llm = new ChatOpenAI({
        apiKey: openai_key,
        model: "gpt-4o-mini",
      });
      const response = await prompt.pipe(llm).invoke({ messages, userInfo });
      return {
        messages: [response],
      };
    }

Hello! We recommend passing the common configuration in RunnableConfig["configurable"] especially if the value does not need to be updated.

graph.invoke({ ... }, { configurable: { name: "Bob", age: 25 } })
