TypeError: Cannot read properties of undefined (reading 'nodeData')

[AmreshSinha]

I was trying to open a workflow
specifically this one: https://openart.ai/workflows/discus_disastrous_37/free-digital-human/bcculjSnGEcDuGhoNhkd
on a freshly installed comfyui with manager
and after installing all the missing custom nodes from manager it started to throw this error:

Platform: Apple M3 Pro Macbook

Loading aborted due to error reloading workflow data

This may be due to the following script:
/extensions/ComfyUI-VideoHelperSuite/js/VHS.core.js

I am not sure as to why this is coming up. I was not able to find any existing issue on this as well.

I tried debugging (jk just added some print statements)

and interestingly it printed it 2 times. First time it logged out a class. the second time undefined sadly.

Note: I am a newbie to comfyui.

VHS includes code to assist in migrating of older workflows like this one, but it seems there's been changes to ComfyUI itself that break the method I was using to do so. I'll push a quick fix to ensure you don't get an error on load, but some links will need to be manually fixed.

VHS added connections for audio input and output in an overly convoluted VHS_AUDIO format for internal use. A number of other custom nodes adopted the format since it was the only option available. Since then ComfyUI introduced a native AUDIO format which is much nicer for actual usage which VHS has swapped to, but it requires adding in "Audio to legacy VHS_AUDIO" and "Legacy VHS_AUDIO to Audio" nodes to maintain compatibility with other nodes that haven't updated.
