Hello,  
I am using Xano for my authentication. It use to work perfectly.  
Now, I get the error:  
wwLib.wwFormula.getValue is not a function  
I am not sure where this formula is even used in my logic, i presume something WeWeb used to make the login functionality.  
The login works fine on testing mode, only breaks on the published environment.  
Thanks in advance

Hi, for everyone having this issue please publish your project again, it should works. We released a new version of our Xano plugins and a last missing piece took more time than expected to be live in the editor causing the bug.

Sorry for the inconvenience!
