comfyui-frontend-package==1.41.15 Is breaking a lot of workflow and nodes.

[RayHell]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

Load everything correctly.

Actual Behavior

commit: abc87d3
Most of my workflow have this issue at load
Comfyui Cannot read properties of undefined (reading 'addEventListener')
They are completely different from each other but have the same bug.
Some custom nodes are loaded correctly but when I choose to add them to the canvas, nothing happen.
Downgrading to commit from 5 hours ago 980621d that use comfyui-frontend-package==1.39.19 fix the issue.

Steps to Reproduce

Update to commit abc87d3 and try to open your custom workflows.

Loading aborted due to error reloading workflow data
TypeError: Cannot set properties of undefined (setting 'readOnly')

Same here, pretty much none of my workflows that i use, work anymore...

Not sure this is the error, but perhaps, and i case it helps

Even default stock ComfyUI workflows dont work (and many of the ComfyUI stock nodes)

Did pip install comfyui-frontend-package==1.39.19 for now thanks to the original poster
Fixed the issue. Without having to do any git revert or checkouts, an easy temporary fix for anyone running into same issue.
(activate your ComfyUI environment first)

Can you share your workflows causing issue?

Think most, even stock default ComfyUI ones (like the latest Portrait Relight, LTX-2 etc.
I sorted by latests non api ones, just to check if it was my own workflows that caused issues. But same happened with ComfyUI stock ones. But i can install the latest frontend again, to be more specific

Edit: took a little screenshot/video. While it wasnt easy to see in the video, I clicked the LTX-2 latest workflow
(but even the stock "empty" workflow when you start up comfy empty has node errors)

It might be due to some old custom node pack or something, but if there is an easy fix. And i see you are already on the case ;-)

I can't create any API nodes. I click on them and nothing happens! nothing in the console either.

thanks for the "pip install comfyui-frontend-package==1.39.19" tip!

Looks like @dante01yoon is fixing it though so the "downgrade" of frontend package might not be needed much longer ;-)

Thanks Dante ;-) that was quick.
Seems to work great now,

(and intrigued by the new "app" feature.. new things to explore ;-)
