ffi.from_handle() detected that the address passed points to garbage

Describe the bug
My app crashes while doing load test

To Reproduce
Here is my code

from socketify import App, Request, Response

app = App()

async def hello(res: Response, req: Request):
    await res.get_json()
    res.end("Hello worldddddd!!!")

app.get("/", hello)
app.listen(8000, lambda config: print("Listening on port http://localhost:%d now\n" % config.port))
app.run()

then I was tried to do load test with wrk

(venv) ○ wrk -t10 -c10 -d30s "http://127.0.0.1:8000/"
Running 30s test @ http://127.0.0.1:8000/

then the error occurred, it said as below

Expected behavior
all is fine previously while doing simple load test, but this error happens when I add await res.get_json()

Desktop (please complete the following information):

• OS: MacOS Sonoma 13

Additional context
I want to migrate my app from FastAPI to socketify, since the simple load test giving me about 10x times faster using socketify, but when I try to do simple body json read, my app crashes and I would be very happy for any resolutions!. thank you!

regards
