"Edit SEG_ELT" Node unable to deal with SEGS not found?

[gobshyte]

Unless I'm missing something, it seems there is no way to use the "Edit SEG_ELT" in a workflow where segs are not found?

If I decompose empty segs then assemble, there is no issue.

But if I put "from SEG_ELT" into "edit SEG_ELT" (in cases where no SEGS were found) we get

'NoneType' object has no attribute 'cropped_image'

ComfyUI\custom_nodes\ComfyUI-Impact-Pack\modules\impact\segs_nodes.py", line 953, in doit
cropped_image = seg_elt.cropped_image if cropped_image_opt is None else cropped_image_opt
^^^^^^^^^^^^^^^^^^^^^

This seems to make it impossible to use the "SEG's isn't empty" node when using "Edit SEG_ELT" ?

Why don't use apply SEG's isn't empty before Decompose (SEGS)?

I have tried with the SEG's isn't empty node in many places, here are some examples:

Same error on the Edit SEG_ELT node ('NoneType' object has no attribute 'cropped_image')

Same error on the Edit SEG_ELT node ('NoneType' object has no attribute 'cropped_image')

This one almost seems to be getting there, as it stops complaining about each node as I connect them, however, the crop_region_opt input is a custom class with no primitive so I got a bit stumped.
The error at this point is ('tuple' object has no attribute 'crop_region')

OK, so I now have a functional workflow that can edit the SEGS and still handle missing SEGS, but it is dependent on a change in the segs_nodes.py

The worflow looks like this:

But it requires this exception to handle a 'none' input into the Edit SEG_ELT node:

I did look at possibly returning an empty SEG_ELT class or something, so the Assemble (SEGS) would essentially return the same thing as EmptySEGS, but I couldn't figure out how to do that, sorry!

Actually you should not approach that way.

That does not seem to work? I get no output and SEGS test boolean after the switches seems to be "DisplayText"?
