Minimax H3 Latent Upscaler Error

### Custom Node Testing

- [ ] 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)

### Your question

H3 can operate normally, but the Minimax H3 Latent Upscaler reports an error when turned on。I am using the dasiwa workflow。

### Other

_No response_

Start by reproducing the dasiwa workflow with the Minimax H3 Latent Upscaler and confirm whether the failure persists with custom nodes disabled. Read comfy/ldm/minimax/model.py around line 654, then trace the call from comfy_extras/nodes_custom_sampler.py:1055 and compare the reported tensor shapes. Done means identifying the incompatible inputs and confirming the workflow completes without the shape-mismatch error.
