Selector does not recognize nested nodes after pressing Cancel run > Progress (...)

"Unknown error" is displayed, the console says:

got prompt

KeyError: 'MyNode'

The MyNode isnt the first one after / before the selector, it is an unrelated one to the part where I press the buttons

Otherwise it works fine and it is a really great addition to workflows

Didn't find "MyNode" in the code so I have no idea where this error come from. Could you make a minimum workflow that can reproduce this error?

I see I made a mistake here. Posted it in the wrong extension, sorry for the confusion (it was about the comfyui image picker not selector)
