How to handle exceptions?

[ansorre]

Is there a way to catch an exception and resume execution from a specific node? For example, my workflow requires a face restore at some point, and yet a face is not always present in the image. When the image does not contain a face, the entire workflow hangs due to an exception raised by ComfyUI complaining that there is no face.

What is your workflow?

No way, I didn't, this is still a serious problem in ComfyUI.

Can you please add some screenshots?

Here we go. The promt is "a sunny day on the beach in a tropical island" and since there are no faces the exception rises.

I guess with #4230 it should be possible to write if/else nodes and even handle for face in faces loops with nodes. It would be interesting to see some new solutions.
