lmao i don't even know how or WHERE that could occur; out of curiosity, were you possibly dragging a non-square reticle?

actually, googling the "right is less than left" error seems to suggest that it's happened in webUI previously; are you possibly using an outdated webUI?

[jwvanderbeck]

Webui is up to date and I tried both a square and non square. That said I THINK I know what caused this. I ran into the same error in the webui after posting this, and in that case the error was occuring because I had the mode set to inpaint but had not drawn a mask.

Here I was also not drawing a mask as what I was hoping to do was simply a standard img2img on the whole tile as if I had passed the tile into the im2img (not inpaint) function. Maybe this is not supported though or I had the wrong options set.

[zero01101]

lol somewhat ironically the links both mentioned no mask being painted, but in this case.... yeah, that should definitely be a supported use case; for example i can take my default testfish

and simply change the prompt to "a submarine" and slap img2img over it

technically a mask should be supplied whether or not you've manually defined one, it just might be a 100% blank or full mask depending on your invert mask option setting, but i still can't quite work out how no mask would've been passed to the API in the first place :/

[illusive-c]

I got that too. Click on the blue or red mask icon:

or, clear out your mask and it'll go away
