Run the readme.md example Error: TypeError: 'granian._granian.RSGIHeaders' object is not subscriptable

It seems like a granian bug, and it works when I use the emmett develop --interface asgi command that works out.

example

from emmett import App, request, response
from emmett.orm import Database, Field, Model
from emmett.tools import requires, service


class Task(Model):
    name = Field.string()
    is_completed = Field.bool(default=False)


app = App(__name__)
app.config.db.uri = "postgres://username:password@localhost/foo"
db = Database(app)
db.define_models(Task)
app.pipeline = [db.pipe]


def is_authenticated():
    print(request.headers)
    return request.headers["Api-Key"] == "foobar"


def not_authorized():
    response.status = 401
    return {"error": "not authorized"}


@app.route(methods="get")
@service.json
@requires(is_authenticated, otherwise=not_authorized)
async def todo():
    page = request.query_params.page or 1
    tasks = Task.where(lambda t: t.is_completed == False).select(paginate=(page, 20))
    return {"tasks": tasks}

My Test

import requests

url = "http://localhost:8000/todo"
headers = {"Api-Key": "foobar"}
response = requests.get(url, headers=headers)

if response.status_code == 200:
    tasks = response.json()["tasks"]
    print(tasks)
else:
    print("Error:", response.status_code, response.json())

Case: Add an additional question when I use emmett develop --interface asgi
I generate a new request whose headers["Api-key"]="not_foobar", otherwise condition will not work properly.
Expected: otherwise return {"error": "not authorized"}

response = requests.get(url, headers=headers)

My bad I didn't check the README example was still valid with 2.5
