Nucleus

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

I merged the shards of Nucleus with the z_image script... i t uses QwenVL3 and the flux2 VAE... so i thought it might work ... nah... na it doesn't ^^ ... see error log (attached in "other")

PS: i DID try to use it with qwen3 instead of qwen3VL .. but we didn't get to the part where it blows up because of that i think ^^

### Actual Behavior

comfy go BOOM on Nuc

### Steps to Reproduce
