I’m upgrading my app to VueJS 3. I read that you could keep the same components. But I have an error in the console now, although I didn’t change anything. Here is my component:
<template>
<v-container>
<div
@click="onClick"
@mousemove="onMouseMove"
id="menu3D"
style="background-color: transparent; position: fixed; left: 20px; width:15%; height:100%;">
</div>
<v-row class="text-center">
<v-col
class="mb-5"
cols="12"
>
<h2 class="headline font-weight-bold mb-3">
Accueil
</h2>
<v-row justify="center">
<p>
Client: {{ JSON.stringify(client)}}
</p>
<p>
Mouse: {{ JSON.stringify(mouse)}}
</p>
<p>
Container: {{ JSON.stringify(container)}}
</p>
</v-row>
</v-col>
</v-row>
</v-container>
</template>

And here is the error I have in the console with VueJS 3:
three.module.js?5a89:24471 Uncaught TypeError: 'get' on proxy: property 'modelViewMatrix' is a read-only and non-configurable data property on the proxy target but the proxy did not return its actual value (expected '#<Matrix4>' but got '[object Object]')

If anyone has got a clue, thanks in advance…
