AttributeError: module 'pydantic' has no attribute 'SecretField'

[Vuizur]

I have a Python project that uses spaCy, which currently doesn't support pydantic v2. So I currently have pydantic version 1.9.2 installed.

I wanted to make a quick server like this (no idea if this code is correct):

from litestar import Litestar, get
from russian_text_stresser.text_stresser import RussianTextStresser

# Create an instance of the RussianTextStresser class
stresser = RussianTextStresser()


# Define a route for the stress_text function
@get("/stress_text/{text}}")
async def stress_text(text: str) -> str:
    # Return the output text as a JSON object
    return stresser.stress_text(text)

app = Litestar([stress_text])

But when I run it using litestar run, I get this.

(russian-text-stresser-py3.10) PS C:\Users\hanne\Documents\Programme\add-stress-to-epub> litestar run

How could I fix this? Thanks for the help!

Python: 3.10.2
litestar-version: 2.0.0b4

Please update to pydantic 1.10.12
