UModal There are no focusable elements inside the <FocusTrap />

I recently start using nuxt and i'm trying to open a UModal. With my current code, the modal open sometimes. (when it doesn't, shows the message There are no focusable elements inside the <FocusTrap />). here's the gist with the file where i called the modal and the modal file itself: https://gist.github.com/JonatasBSM/f9fc4ae0b36eaca683690ebd951c052c
