Wan 2.1 frame to frame run problem

Hi everyone,
I’m kind of new to ComfyUI. I grabbed the official workflow from GitHub for wan2.1 start/end frame ( https://github.com/raindrop313/ComfyUI-WanVideoStartEndFrames?tab=readme-ov-file ). The problem is that, after installing all the nodes, I’m getting the issue you see in the screenshot, and I honestly have no idea how to fix it.

From the node install manager, there is a “teacache” listed, but it’s not the right one. I’m totally stuck.

I checked for missing nodes and none show up, I restarted everything, etc., but no luck.

Thanks a lot for any help!
