Unhandled Runtime Error TypeError: der.onStale is not a function

[kevincantstop]

same issue. It might be something wrong with r3f extension I think...

App.jsx

import * as THREE from 'three'
import React, { useRef, useState } from 'react'
import { Canvas, useFrame } from '@react-three/fiber'
import { getProject } from '@theatre/core'
import extension from '@theatre/r3f/dist/extension';
import { SheetProvider } from '@theatre/r3f'

import studio from '@theatre/studio'

studio.initialize()
studio.extend(extension)

import "./app.css"

// our Theatre.js project sheet, we'll use this later
const demoSheet = getProject('Demo Project').sheet('Demo Sheet')

const App = () => {
    return (
        <Canvas camera={{position: [5, 5, -5], fov: 75}}>
            <SheetProvider sheet={demoSheet}>
                <ambientLight/>
                <pointLight position={[10, 10, 10]}/>
                <mesh>
                    <boxGeometry args={[1, 1, 1]}/>
                    <meshStandardMaterial color="orange"/>
                </mesh>
            </SheetProvider>
        </Canvas>
    )
}

export default App

Folks, can you share a reproduction on codesandbox/stackblitz?

Same problem here, after loading the theater editor all seemed to be working fine... But when I tried to create a snapshot with the camera icon, the same weird error. I hope it can be solved in further releases. Thanks for the good work!

Had the same issue, very disappointing.
