Fastapi: "POST /items/ HTTP/1.1" 422 Unprocessable Entity

[pawanm09]

Testing the post request of Fastapi.

But, every time I get 422 Unprocessable Entity Error.

from typing import Optional

from fastapi import FastAPI
from pydantic import BaseModel
import uvicorn


class Item(BaseModel):
    name: str
    description: Optional[str] = None
    price: float
    tax: Optional[float] = None


app = FastAPI()


@app.post("/items/")
async def create_item(item: Item):
    print(item)
    return item

Running it on gcp using : uvicorn testing:app --host 0.0.0.0 --port 5000

Request Structure:
Post Request on the route:http://35.132.89.173:5000/items/
body: { "name": "nmsaey", "price":34}
header: { Content-Type: application/json}

Version:
python: 3.6.9
fastapi: 0.60.1
pydantic: 1.6.1

The payload { "name": "nmsaey", price:34} doesn't seem to be properly json formatted.

Try to put price in quotation marks: {"name": "nmsaey", "price": 34}

@marodev Sorry, it was just a typo.

price is in quotes. I will update the question.

[marodev]

How do you send the HTTP POST request? With a tool like Postman or by using a Python script?

[pawanm09]

@marodev
Through Postman

It works just fine here, command used to test:

curl -X POST "http://0.0.0.0:8000/items/" -H  "accept: application/json" -H  "Content-Type: application/json" -d "{\"name\":\"nmsaey\",\"price\":34}"

Running it on gcp

I'll assume you are running it inside a virtual machine since the host looks very similar to what a vm makes http://35.132.89.173:5000/items/

Make sure when creating the vm you click the 'Allow HTTP traffic' option
If that doesn't work check if you still have the vm ssh terminal open # yes dumb but from personal experience (:man_facepalming:) you should try

[marodev]

Works for me as well. Does it look similar to this:

Thanks for your response

The problem was in Postman.

Everything was fine using code.
