Undefined variable: script_language

I'm trying to use neural using a local model that supports OpenAI compatible API. I get this error when I try `:Neural hello` or any other query/neural command:

```
Invalid provider:
Error detected while processing function neural#Prompt[15]..neural#Run[15]..neural#GetCommand[2]..82_GetScriptExecutable:
line 1:
E121: Undefined variable: script_language
Error detected while processing function neural#Prompt[15]..neural#Run:
line 15:
E714: List required
Press ENTER or type command to continue
```

This is the vim version:
```

```

I tried changing the `GetScriptExecutable` function to always return python3 :D but unfortunately that just causes more errors like:
```
Invalid provider:
Error detected while processing function neural#Prompt[15]..neural#Run[15]..neural#GetCommand:
line 3:
E121: Undefined variable: script
E116: Invalid arguments for function neural#Escape(l:provider.script)
Error detected while processing function neural#Prompt[15]..neural#Run:
line 15:
E714: List required
```

Not sure what I'm doing wrong. Probably a lot.

Oh also, my vimrc has this: (changed the ip for privacy)
```
let g:neural = {
\ 'providers': [
\ {
\ 'openai': {
\ 'url': 'http://x.x.x.x:8000/v1',
\ 'api_key': '',
\ },
\ },
\ ],
\}
```

I tried removing `v1` but that didnt work either, then again, I'm not sure that it's even getting near to using the url yet
