If you ran into the above error before, one of the most common causes is forgetting to define exactly one root element.
So, if your code looks like this:
<template x-if="loading"> Loading... </template>You need to change it to this (instead of a div you may use any other valid HTML element):
<template x-if="loading"> <div>Loading...</div></template>As stated in the Alpine.js docs, template tags may only contain one root element, and text in itself does not qualify as an element.
I hope this post helped you! If you have any questions, hit me up on X 😊.
