Thank you for all of that information @Jehale. We think the problem is likely to do with the MacOS beta version.
In regards to the AI issue, as it’s still in it’s early stages some prompts may produce unexpected errors. I don’t see anything wrong with your prompt so I will file it as an issue, but for now I’d recommend rephrasing the prompt slightly and trying it again a few times to see what you can generate.
We also have a post on this forum and over at the blog which outlines a guide for the best practices when using the Create Copilot. If you haven’t checked that out yet I would highly recommend it!
