LatentUpscale error for workflow with ipadapter, I don't know if it's tiled diffusion or the ipadapter generating the error, please help!

[KennyChan3389]

When I run IterativeLatentUpscale with the ipadapter node to build a partition masking workflow, it still produces an error.

Error occurred when executing IterativeLatentUpscale. module 'comfy.sample' has no attribute 'prepare_mask'

It's my workflow. [ipa.json](https://github.com/user-attachments/files/15595337/ipa.json)

I'm not sure if it's the ipadapter or the tiled diffusion anymore, I'll try to contact the respective authors, this will serve as a place to store questions for now. Hopefully it will get resolved
