This happens only if execution is cached? Ie. trying to generate again with same parameters and same seed.

It kinda looks like that from the console log, the last prompt didn't produce an image because nothing changed.

I wasn't able to reproduce it though, even with fixed seed / cached prompt. Which version of the plugin are you using?

[1MB4R0SS4]

Version 1.24.0

with previous versions, I had similar problems. I would try to generate an image, and although the terminal showed it was done, nothing appeared in krita. I had to attempt generating the image several times to make it work, but there were no error messages about it. now, sometimes an error message appears, and I’m unable to regenerate any images later on, so I have to reload krita to make it work again.

The "no image" case is handled now and there's some more error reporting for spurious connection issues.
