Can you share the error message you ran into?

Hi Robert, yes sure i added the stacktrace below. And i noticed that the code snippet had a small error, this is the corrected version:

from openai import OpenAI


key = ''
openai_client = OpenAI(api_key=key)
thread_id = openai_client.beta.threads.create().id
print(openai_client.beta.threads.messages.list(thread_id=thread_id))

Traceback (most recent call last):

@JonasRueegsegger try just update openai version

pip install --upgrade openai

it helps me, because there is a new version released at 31th of March

[RobertCraigie]

ah I think you're on an older version that didn't set the minimum pydantic version properly. please update to the latest version and re-open this if you're still running into this.
