Status code 422

[catch-n-release]

Trying to run example code

---

from fastapi import FastAPI
from pydantic import BaseModel
class Item(BaseModel):
name: str
description: str = None
price: float
tax: float = None
app = FastAPI()
@app.post("/items/")
async def create_item(item: Item):
return item

---

With a request body as
{
"name": "Foo",
"description": "An optional description",
"price": 45.2,
"tax": 3.5
}

---

Now,
Requesting through interactive API documentation (provided by Swagger UI)
gives the correct response,
while if I request the same though POSTMAN returns me status code 422 with the following:
{
"detail": [
{
"loc": [
"body",
"item"
],
"msg": "field required",
"type": "value_error.missing"
}
]
}

Please if someone could explain it.

Sending it as Content-Type application/json in Postman? Log/print the item so you can see what's showing up and check the headers. Everything looks fine and since it's working from Swagger UI ...
