Problem
The
NunchakuFluxDiTLoadernode crashes during initialization when broken symbolic links exist in themodels/diffusion_models/folder, preventing ComfyUI from loading.Error:
Root Cause
In
nodes/models/flux.pyline 99,INPUT_TYPES()usesfolder_paths.get_full_path_or_raise()which throws an exception when encountering broken symlinks or missing files during the model list scan.Solution
Replace
get_full_path_or_raise()withget_full_path()and skipNoneresults (broken symlinks/missing files) instead of crashing.Changes
folder_paths.get_full_path_or_raise()→folder_paths.get_full_path()if safetensor_path is None: continueto skip invalid pathsTesting
Tested with broken symlinks in
models/diffusion_models/- node now loads without errors and properly skips invalid files.
