the example doesnt seem to work

import uvicorn
from fastapi import FastAPI
from profyle.fastapi import ProfyleMiddleware

app = FastAPI()
# Trace all requests that match that start with /users
# with a minimum duration of 100ms and a maximum stack depth of 20
app.add_middleware(
    ProfyleMiddleware,
    pattern="/users*",

)

@app.get("/users/{user_id}")
async def get_user(user_id: int):
    return {"hello": "user"}

uvicorn.run(app, host="127.0.0.1", port=8080)

i get the error mentioned in the title. your library seems really cool and i would really like to use it

Thanks for reporting, I will take a look to this issue. Can you provide the entire error trace? Also I need more info about your operating system.

This is due to windows permissions, simply setting delete=False on the NamedTemporaryFile fixes it: https://github.com/vpcarlos/profyle/blob/main/profyle/application/profyle.py#L45
