Timeouts for agents

By default, LangChain will wait indefinitely for a response from the model provider. If you want to add a timeout to an agent, you can pass a timeout option, when you run the agent. For example:

import { initializeAgentExecutorWithOptions } from "langchain/agents";
import { OpenAI } from "@langchain/openai";
import { Calculator } from "@langchain/community/tools/calculator";
import { SerpAPI } from "@langchain/community/tools/serpapi";

const model = new OpenAI({ temperature: 0 });
const tools = [
  new SerpAPI(process.env.SERPAPI_API_KEY, {
    location: "Austin,Texas,United States",
    hl: "en",
    gl: "us",
  }),
  new Calculator(),
];
const executor = await initializeAgentExecutorWithOptions(tools, model, {
  agentType: "zero-shot-react-description",
});

try {
  const input = `Who is Olivia Wilde's boyfriend? What is his current age raised to the 0.23 power?`;
  const result = await executor.invoke({ input, timeout: 2000 }); // 2 seconds
} catch (e) {
  console.log(e);
