Hello!
I created a survey form from my feature service. I went to add a field in the XLSForm and it will not publish because of the error in the picture below:

I have not done anything to the original feature service and have not moved any of my files into different folders since the beginning. One day it just wasn't working anymore. I don't want to have to redo this survey since its linked to my WebApp so I hope there's an answer!
Thank you!
