UploadFile file in FastAPI integration appears to be `starlette.UploadFile`

[Nnonexistent]

I'm trying to get a FileUpload instance of proper type inside a resolver in a FastAPI integration of strawberry. However I always get starlette.UploadFile instead of fastapi.UploadFile.

Describe the Bug

I'm following these guides: https://strawberry.rocks/docs/guides/file-upload and
https://strawberry.rocks/docs/integrations/fastapi.

I expect file to be a fastapi.UploadFile. Instead I'm getting starlette.datastructures.UploadFile.

scalar_overrides argument doesn't seems to change anything.

I'm not sure if my configuration is incorrect or it's a bug.

Reproducible example (copy/paste to ipython or similar with all used packages installed):

import io
import json

import httpx
import strawberry
from fastapi import FastAPI, UploadFile
from strawberry.fastapi import GraphQLRouter
from strawberry.file_uploads import Upload


# Arrange


@strawberry.type
class Mutation:
    @strawberry.mutation
    async def handle_file(self, file: Upload) -> str:
        return str(type(file))  # <- will check type here


@strawberry.type
class EmptyQuery:
    nothing: None


schema = strawberry.Schema(
    EmptyQuery,
    Mutation,
    scalar_overrides={UploadFile: Upload},  # <- this changes nothing :(
)

graphql_app = GraphQLRouter(
    schema=schema,
    multipart_uploads_enabled=True,
)
app = FastAPI()
app.include_router(graphql_app, prefix="/api")


# Testing


client = httpx.AsyncClient(transport=httpx.ASGITransport(app=app), base_url="http://test")

query = """
mutation TestMutation($file: Upload!) {
    handleFile (file: $file)
}"""

payload = {
    "operations": (
        None,
        json.dumps({"query": query, "variables": {"file": None}}),
        "application/json",
    ),
    "map": (None, json.dumps({"file": ["variables.file"]}), "application/json"),
    "file": ("test.txt", io.BytesIO(b"")),
}
response = await client.post("/api", files=payload)

print(response.json()["data"]["handleFile"])  # <class 'starlette.datastructures.UploadFile'>
