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.
