Thank you for amazing upscaler.

Sometimes I am getting this error.

Are you using the official replicate model or something self hosted? Did you tried another input image?

[Alexandr-git-bot]

I have the same problem, I changed the original image, but it still gives an error.

[Nikitosina]

For me, this happens when I set creativity parameter to 0

[philz1337x]

you can't set

For me, this happens when I set creativity parameter to 0

You can't set creativity to 0. You need to choose a value >0
