Ain't Another Head Swap - Workflow Reviews

⚠️ Warning for users trying this workflow I spent several hours trying to make this workflow run, but it never worked on a clean and properly set up ComfyUI environment. I want to clearly document what I tried, so others don’t waste the same amount of time. What I did Fresh ComfyUI install (latest version) Proper CUDA / PyTorch setup Installed Visual C++ Redistributables (x64) Installed all required custom nodes via ComfyUI-Manager Restarted ComfyUI multiple times Verified models and LoRA paths Rebuilt the workflow from scratch Removed optional nodes (ControlNet, extras, etc.) What happened ComfyUI consistently fails with: “Cannot execute because a node is missing the class_type property” The reported Node ID (e.g. #289) does not exist on the canvas The error persists even after removing visible problematic nodes Copying nodes to a new canvas does NOT fix it Conclusion This workflow JSON appears to be corrupted or generated with an incompatible / deprecated node schema. It is not an environment issue and not a user setup mistake. Recommendation Please do NOT try this workflow unless a fixed JSON is provided The author should re-export the workflow from a clean ComfyUI instance At minimum, the workflow should be marked as broken / outdated I am posting this to prevent others from losing hours debugging something that cannot be fixed on the user side.
