### Steps to Reproduce

1. test_sentry.py

# -*- codong: utf-8 -*-
from fastapi import FastAPI
from sentry_sdk.integrations.asgi import SentryAsgiMiddleware
from starlette.testclient import TestClient


def test_sentry():
  app = FastAPI()

  @app.get("/")
  async def index():
    return 'Ok'

  asgi_app = SentryAsgiMiddleware(app)

  with TestClient(app=asgi_app) as client:
    rsp = client.get('/')
  assert rsp.status_code == 200

1. pytest test_sentry
2. test_sentry.py F [100%]

Expected Result

test_sentry Ok

Actual Result

In version sentry-sdk=1.5.4 all work Ok

[tonal]

@simonkern Yes. After add sentry_sdk.init() test work Ok

[antonpirker]

I just checked and you are right @lsmith77 . It should be totally fine to not call init() . So I will do some tweaking so no errors are thrown in 1.5.5 when init() is never called.

Thanks for bringing this up!
