[BUG] float() argument must be a string or a real number, not 'Tree'

[xxlukexx]

Before you start Verify the following:

1. That your ComfyUI is up to date - YES
2. That the extension is up to date - YES
3. That the issue isn't in the "Known Issues" section in the README - YES

Describe the bug When attempting to schedule (whether using a lora of just part of the prompt) I get the following error. This was working fine until recently. I'm not sure if it changed when I updated comfyui or when I installed other custom nodes. However, it still occurs even when I disable all other custom nodes through the manager (other than the manager itself).

I think this is related to lark, here are the versions I have installed in my venv:

lark 1.1.9 lark-parser 0.12.0

I've tried debugging this and the first time tostep is called (when the value of i in CollectSteps.scheduled = -1), the value of s is : Token('NUMBER', '0.5') and it succeeds.

The second time tostep is called (when i = -2) the value of s is Tree('prompt', [Token('PLAIN', 'by akira toriyama')])

Error occurred when executing PromptToSchedule:

I think you may need to remove lark-parser from your virtualenv. It seems to be an old version of lark or something.

I don't know why there are two lark packages, but my virtualenv only has lark 1.1.9 and I can't reproduce this issue.

Thanks, removing both and then doing pip install -r requirements.txt fixed this for me.
