Extension does not properly initialize on SD.Next

[redrum-llik]

Hello! Was really impressed by the description of the extension and wanted to give it a try on my local SD.Next installation. After installing from URL and restarting the whole process, I saw the following in the console:

18:34:36-822022 ERROR    Calling script: extensions\sd-webui-neutral-prompt\scripts\neutral_prompt.py/ui:

Some screenshots of the UI:

(On the above image, "Neutral Prompt" tab is expanded but it has no content.)

On an attempt to generate something I get the following exception:

I was not entirely sure if you aim to have this extension compatible with SD.Next since it is not explicitly stated on the README, but if you do, I am happy to assist with any details you may need from me.

Thanks for the report, I am working on something else currently but I'll try to take a look this week. PRs are welcome if you want this fixed sooner.
