from agents import Agent, Runner
import asyncio

spanish_agent = Agent(
    name="Spanish_agent",
    instructions="You translate the user's message to Spanish",
)

french_agent = Agent(
    name="French_agent",
    instructions="You translate the user's message to French",
)

orchestrator_agent = Agent(
    name="orchestrator_agent",
    instructions=(
        "You are a translation agent. You use the tools given to you to translate."
        "If asked for multiple translations, you call the relevant tools."
    ),
    tools=[
        spanish_agent.as_tool(
            tool_name="translate_to_spanish",
            tool_description="Translate the user's message to Spanish",
        ),
        french_agent.as_tool(
            tool_name="translate_to_french",
            tool_description="Translate the user's message to French",
        ),
    ],
)
result =Runner.run_sync(orchestrator_agent, input="Say 'Hello, how are you?' in Spanish.",run_config=config)
print(result.final_output)

OUTPUT:
I am sorry, I cannot fulfill this request. The tool returned an error. Please try again.

So why this issue occurs

When I remove the unknown config object parameter, this code snippet consistently works as expected. Can you share the full code if possible? Also, enabling debug-level logging by adding the lines of code at top of your code may help:

import logging
logging.basicConfig(level=logging.DEBUG)

I added a config.py file to centralize and securely manage configuration variables, such as API keys and environment settings. Since I’m currently using the Gemini API in place of OpenAI (due to being a student)
Here is my config.py file
