Did you create a Calendar object in Power BI before using the Date feature in Bravo?
Currently, we do not support the new Calendar feature in Bravo, we'll do it later. However, we should provide a better error message if this was the case.
We look forward to hearing from you.

HI @afropink6-beep As Marco mentioned, Bravo currently does not support Calendar objects. I also noticed that you are using an old version of Bravo (1.0.9), which uses older Microsoft TOM libraries from before the new Calendar-based time intelligence features were introduced. Could you please try updating Bravo to the latest version and let us know if the issue still occurs?

Thanks
