@vishnumg Assistants is still in preview, so you'll need to target the preview API version == "2024-05-01-preview" (API reference).

That being said, I can't reproduce the error that you're seeing here. Can you try the preview API version and see if that works for you?

[hayescode]

@vishnumg your API version is 2023, before Assistants existed

Would you please clarify this @leonprompter ? I had a similar issue here 'https://github.com/microsoft/semantic-kernel/discussions/9002#discussioncomment-10774526' and am interested in related solutions if you don't mind.

I'm getting the same error and I'm unable to make any progress. I've tried different python versions and endpoints. I've verified the endpoints work but I am unable to create an assistant instance.

I think this should be resolved now, please re-open if this is still an issue.
