With WebGPU, DirectionalLight + castShadows crashes

[verekia]

Description

With WebGPURenderer, DirectionalLight works fine but not with castShadows enabled.

Reproduction steps

It crashes on this line of TextureNode.js.

TextureNode.js:52 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'channel')
    at Proxy.getDefaultUV (TextureNode.js:52:12)
    at Proxy.construct (TextureNode.js:87:1)

    getDefaultUV() {

        return uv( this.value.channel ); ❌

    }

Code

See reproduction repo

Live example

I could not reproduce the bug in a live playground due to the top-level await of WebGPURenderer, sorry.

Here is a minimal reproduction repo: https://github.com/verekia/r3f-webgpu/tree/three-direction-light

Vanilla reproduction: https://jsfiddle.net/joekm4n2. Narrowed it to the use of a textured material combined with shadow maps.

Thanks for making it easy to reproduce the error. Regarding the example in r3f, I think that for benchmark purposes r157 brings some important improvements and others we are developing here.
