Troubleshooting

Error : `LTXVInContextSampler LTXVInContextSampler.sample() got an unexpected keyword argument 'optional_cond_image'. Did you mean 'optional_cond_images'?

Double click the workspace and re add the LTXV In Context Sampler swapping the input and output nodes from the old LTXV In Context Sampler to the new.

Join the input image from option_cond_image to option_cond_images.

There will still be a problem. See the next error below.

Error : LTXVInContextSampler 'NoneType' object is not iterable

Open the file .\ComfyUI_windows_portable\ComfyUI\custom_nodes\ComfyUI-LTXVideo\easy_samplers.py

Replace line 685 from,

optional_cond_indices=None,

to

optional_cond_indices="0",

Restart ComfyUI and try again.
