Error when deploying form

Hello, I’m setting up the project in my local machine and after I deploy it and I want to open the form, I receive an error. Here I attach the image of the error. I created the project as Workstation.

Welcome to the community, @CristhianFerreira! Even though you are on a self-hosted server, you could still validate your XLSForm through this online validator to see if your form has any syntax issues.

I’m building the form using the built-in tool. I downloaded the form and I validated it with the online validator but the structure of the form is fine.
