HashModel doesn't work on pydantic

[amevide998]

code :

from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware
from redis_om import get_redis_connection, HashModel

app = FastAPI()

app.add_middleware(
CORSMiddleware,
allow_origins=['http://localhost:3000'],
allow_methods=[''],
allow_headers=['']
)

redis = get_redis_connection(
host="redis-11844.c135.eu-central-1-1.ec2.cloud.redislabs.com",
port=11844,
password="pRdcpRkKPFn6UnEFskrDGxrmFbf5T9ER",
decode_responses=True
)

class Product(HashModel):
name: str
price: float
quantity: int

class Meta:
    database = redis

@app.post('/products')
def create(product: Product):
return product.save()

error message :

fastapi.exceptions.FastAPIError: Invalid args for response field! Hint: check that <class 'main.Product'> is a valid Pydantic field type. If you are using a return type annotation that is not a valid Pydantic field (e.g. Union[Response, dict, None]) you can disable generating the response model from the type annotation with the path operation decorator parameter response_model=None.

You can use the older version pip install pydantic==1.10.13 it will resolve the error.
