Why Does My ChatGPT API Code Return a 'Failed Run Status'?

I'm trying to implement a ChatGPT-based chatbot using the API, but every run returns a failed status. I've based my code on documented examples, yet I keep encountering issues. Below is one version of my Python script that I tried:

PYTHONCopied
from openai import OpenAI  

import time

client = OpenAI(api_key=“xxx”)

assistant = client.beta.assistants.create(  
    name=“Code Assistant”,  
    instructions=“You are a code helper for beginners. Write, execute, and explain code to best answer questions.”,  
    tools=[{“type”: “code_interpreter”}],  
    model=“gpt-3.5-turbo”  
)

thread = client.beta.threads.create()

message = client.beta.threads.messages.create(  
    thread_id=thread.id,  
    role=“user”,  
    content=“How does recursion work? Give an example in Python.”  
)

run = client.beta.threads.runs.create(  
    thread_id=thread.id,  
    assistant_id=assistant.id,  
    instructions=“Explain as simply as possible, the user is a beginner.”  
)

while True:  
    run_status = client.beta.threads.runs.retrieve(thread_id=thread.id,  
    run_id=run.id)  
    print(f"Run status: {run_status.status}")  
    if run_status.status == ‘completed’:  
        break  
    time.sleep(1) # Wait for a second before checking again

messages = client.beta.threads.messages.list(  
    thread_id=thread.id  
)

assistant_response = messages.data[0].content[0].text.value

print(assistant_response)

Can someone help identify what might be causing the failed run status and suggest any fixes?

Thanks in advance!
