[Bug]: Error received in CMD window upon completion of image in Photopea

[camoody1]

Is there an existing issue for this?

• I have searched the existing issues and checked the recent builds/commits of both this extension and the webui

What happened?

Starting with a blank 512x512 canvas in Photopea. I created a new image using your plugin and the RealisticVision v5 model. The image completed successfully in Photopea, but I received a very long error in the Stable Diffusion cmd window.

Steps to reproduce the problem

Read Above

What should have happened?

I would assume I should NOT receive any error messages in the cmd window.

Commit where the problem happens

webui: v1.5.1
stable-diffusion-ps-pea: [Previous good version]

What browsers do you use to access the UI ?

Microsoft Edge

I don't think the plugin calls /api/predict endpoint on A1111. I just updaetd my A1111 to 1.5.1, and cannot reproduce the issue.

Is the issue reproduced reliably?

[camoody1]

I've tried creating three images today in Photopea using your plugin and starting from a blank canvas each time. So far, I have not been able to get a single image to process to completion. Each of them eventually gets stuck during processing and just locks up. I have to close my Stable Diffusion cmd window and reopen it to process, again.

The same prompts work fine for me in Automatic1111 and complete without issue. 🤷🏽‍♂️

My inpainting seems to work fine, though. I haven't had any problem with them running to completion.

[camoody1]

Well heck... I just tried several more "from blank" Img2Img jobs and they all completed successfully. I have no idea why I hadn't been able to complete one last night or earlier today. 🤷🏽‍♂️

[huchenlei]

I can confirm that I have had some similar stacktrace printed eariler today. It seems to only happen in the first generation when using the plugin. There is definitely something wrong with A1111.
