AttributeError: 'VAE' object has no attribute 'to'

I've tried various model/vae combos (bf16/fp32) with these nodes, and cannot seem to get it to work. Every time I get through sampling and move to decoding, I get the following error:

!!! Exception during processing !!! 'VAE' object has no attribute 'to'

Traceback (most recent call last):

Any thoughts? I'm using the models directly from the Kijai huggingface page, but the only way I can use Hunyuan currently are the Low-VRAM options which I can't use Enhance a Video with.

did you find a solution? running into the same problem

[neutrinotek]

Yeah... Not sure if yours is the same issue, but mine was an oversight by me. I was using the standard "Load VAE" node instead of the HunyuanVideo VAE Loader.

[elchupacabrinski]

probably not as I just solved it by switching to the builtin hunyuan VAE loader instead of the one this project comes with :D
