Hi Marek L
Greetings & Welcome to the Microsoft Q&A forum! Thank you for sharing your query.
I successfully replicated the scenario in the o1 mini environment without encountering any issues. By utilizing the model catalog, I was able to reproduce the situation in my setup seamlessly. I kindly request that you use this information and verify the scenario on your end as well. If the issues persist, can you please Reach out to the Azure OpenAI support team at csgate@microsoft.com.
