Hi and welcome to the Community, @Pri Scherer! 

I hope you don’t mind but I’ve moved your post out into it’s own topic so it can be addressed separately. 

Can you share a screenshot showing the fields and settings have been selected for the Create Booking action that’s erroring? I’d like to take a closer look at that to see if there’s anything on the set up there that might be causing that error. Please remove/hide any private information (like names, emails, addresses etc.) from any screenshots before sharing.

Thanks for your assistance here, I look forward to your reply!
