[ikkysleepy]

I got this error when trying to use VUE3 with vue-form-json-schema.

I used the vue3 rewrite branch: https://github.com/jarvelov/vue-form-json-schema/tree/vue3rewrite
and tried the simple example.

<template>
  <div id="example-one" class="container mb-3 mt-3">
    <h1>vue-form-json-schema</h1>
    <h3>
      Example #1
      <small class="text-muted">Minimal example</small>
    </h3>
    <p class="lead">
      <span>
        A minimal example showing a simple
        <code>input</code> field.
      </span>
    </p>
    <p class="text-center font-weight-bold">

        >Click here to edit this demo</a
