FastAPI file upload not working with sentry after 1.9.6

How do you use Sentry?

Sentry Saas (sentry.io)

Version

1.9.6

Steps to Reproduce

from fastapi import FastAPI, File, UploadFile
from PIL import Image
import uvicorn
import io

import sentry_sdk
from sentry_sdk.integrations.starlette import StarletteIntegration
from sentry_sdk.integrations.fastapi import FastApiIntegration

sentry_sdk.init(
    dsn=SECRET,
    release="server",
    integrations=[
        StarletteIntegration(),
        FastApiIntegration(),
    ],
    attach_stacktrace=True,
    request_bodies="always",
    send_default_pii=True,
    traces_sample_rate=0.0,
)

app = FastAPI()


@app.post("/predict")
async def predict(file: UploadFile = File(default=None)):
    contents = await file.read()
    Image.open(io.BytesIO(contents)).convert("RGB")
    return {"result": "ok"}


uvicorn.run(app, host="0.0.0.0", port=8888, loop="asyncio", lifespan="on")

Expected Result

{"result": "ok"}

Actual Result

Please remove 'SentryAsgiMiddleware' from your project.
See https://docs.sentry.io/platforms/python/guides/asgi/ for more information.

so, when disabling sentry - all works fine, when adding sentry - it breaks. apparently sentry messes up content of uploaded file.

with version 1.9.8 still got the error.

We managed to work around this problem for now by adding await file.seek(0) before the await file.read() call.
