I sometimes get this error when I click on generate if there is a syntax error in my negative prompt, eg a stray colon

I am getting this error using img2img when I choose Generate.

can you reproduce this with a simple one word prompt like 'house'? and no negative prompt?

So I play around with a1111 alot and can attest that this error gets thrown for a range of reasons.
If it helps the community, here is a list of things that I have done to fix it for the various causes it happens for:

• used a prompt with an invalid syntax - fixed via matching up orphaned brackets

• used ControlNET without placing a copy of cldm_v15.yaml placed in .\models
  download link: https://huggingface.co/webui/ControlNet-modules-safetensors/blob/main/cldm_v15.yaml

• webui-user.bat (on windows) crashes to this error upon launch. fixed it by moving out all subfolders from extensions folder and determining that controlnet needed to manually git pull for the latest - a1111 coudln't do it out of the box because of permissions, so I reset the permissions to very open and ran git pull manually for the nested repo for controlnet extension. webui-user.bat successfully ran after that.

I will add more if other solutions come to mind and if there is interest in this.

My issues may have stemmed from a faulty m.2 SSD (Samsung 980 Pro). I replaced the drive last week and am able to generate it now without this particular error. Thank you for the replies. :)

I am Apple's m2, and I use the latest version of stable-diffusion-webui.
I can run normally with the image generated image, but the error above is reported when the partial redraw operation is performed.

I've gotten this error too. But check your prompts. An unclosed paranthesis with :1.1 can cause this error. Example: (chair, bedroom:1.1. As a best-practice, or for error checking, remove prompts until you find out what's causing the error.

[johnmblaz]

Had this error myself (which led me here). Solved by closed my browser window for Automatic1111 and re-launching it.
