[Bug]: Prompt editing appears to be broken.

[amalmin]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

The prompt "a cat, [black:white:0.25]" results in this error:

VisitError: Error trying to process rule "start": not enough values to unpack (expected 4, got 3)

Steps to reproduce the problem

1. Start webui.
2. Add prompt "a cat, [black:white:0.25]"
3. hit Generate

What should have happened?

I think the syntax is correct. It should have worked.

Additionally, other variants don't work:

[:white:0.25] [white:0.25] [black::0.25]

1.3.1 - b6af0a3809ea869fb180633f9affcae4b199ffcf

This is now working again. I am not sure what changed. It also works with 1.3.2.

Presumably something within my environment changed, but I can't see what that is.

[mp3pintyo]

It gives me the same error. Any idea what you set up differently?

Unfortunately no. I had already updated everything when I posted the issue. Then I went away from it for a day or so, and when coming back it...just worked...infuriatingly. It then continued to work after I upgraded again to 1.3.2.

https://gitcode.net/ranting8323/prompt-fusion-extension the same bug happens on me , tried to install the extension above, so that the bug fixed . suggest to install the extension

[statopre]

Had the same problem. Deleting venv fixed it.

[Saskalex]

Deleting venv/lib/site-packages/lark* instead of whole venv should suffice because the stack trace above seems to hint at a problem with the lark parser toolkit. I had the same problem and this fixed it for me.
