Steps to reproduce Automatically instrument a FastAPI application

What is the expected behaviour? The start of the trace, and possibly one span representing the time to receive the post content.

What is the actual behaviour? A large number of tiny spans are created.

Can you provide an example app that show that behaviour please?

[zacps]

This should work with something simple as:

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def test():
  return "Ok"

Just post a large enough body (json is fine) to see the multiple receive calls.
