Xano API integration issue

Have an error when tried to add Xano API to the platform (till yesterday it worked fine). It's very frustrating because i finally remade all endpoints and pretend to add it to the app. The more frustrating is that i got this error just in 5 minutes before i payed for pro plan. I tried to connect Bravo and Xano multiple times, but the result was the same.

I send my case to Bravo team through this form https://www.bravostudio.app/contact, but don't really sure is it really works or not. Maybe there are another options to receive help?

Question for the community also: if bravo will not can fix it, do you know similar alternatives to make app frontend in no-code and works with Xano?
