AttributeError: 'NoneType' object has no attribute 'to' when using DynamicCraftBatchProcessor

[SSA4]

Hi,

everytime I try to use the DynamicCraftBatchProcessor with the "dynamicrafter_512_interp_v1_bf16.safetensors" model I get this error:

Prompt executed in 8.15 seconds

That is is my Comfy workflow:

I'm having the exact same issue, did you find a fix? The regular image to video workflow works great but when I decided to try the Interpolation workflow I get the same error you're getting.

That particular node is currently not functional, you can use the DynamicrafterI2V -node instead, but I recommend just using Tooncrafter, it works fine for realistic images as well.
