what is wrong with my code?

from langchain.agents import initialize_agent, Tool
from langchain.chat_models import ChatOpenAI
from langchain_community.utilities import SerpAPIWrapper
import os
from dotenv import load_dotenv

Step 1: Load environment variables from the .env file

load_dotenv()
print(f"SERPAPI_API_KEY: {os.getenv('SERP_API_KEY')}")
print(f"OPENAI_API_KEY: {os.getenv('OPEN_API_KEY')}")

Step 2: Retrieve API keys from environment variables

serp_api_key = os.getenv("SERP_API_KEY")
openai_api_key = os.getenv("OPEN_API_KEY")

Step 3: Validate that API keys are available

if not serp_api_key or not openai_api_key:
raise ValueError("API keys are missing. Ensure SERPAPI_API_KEY and OPENAI_API_KEY are set in your .env file.")

Step 4: Initialize tools

search = SerpAPIWrapper(serpapi_api_key=serp_api_key)
tools = [
Tool(
name="Search",
func=search.run,
description="Use this tool to search the web for up-to-date information on job postings."
)
]

Step 5: Initialize OpenAI LLM

llm = ChatOpenAI(model="gpt-4", temperature=0, openai_api_key=openai_api_key)

Step 6: Initialize agent

agent = initialize_agent(
tools=tools,
llm=llm,
agent="zero-shot-react-description",
verbose=True
)

Step 7: Run the agent with a query

result = agent.run("Find software internship jobs posted today.")
print(result)
