FastAPI route - TypeError: root() missing 1 required positional argument when using request object

I get this error:

TypeError: root() missing 1 required positional argument: 'request'

stack trace:

Which I'm able to reproduce with this simple bit of code:

from fastapi import FastAPI, Request
app = FastAPI()

@app.route("/{full_path:path}")
async def root(full_path: str, request: Request):
    print(request.method ,full_path)
    return "HIYO"

I need to access the full path and request object inside the route, and as far as I've been able to find, this is the way to do this. Does anyone know what I'm doing wrong?

I run the script using uvicorn main:app

Cheers

The source code states that this decorator is no longer documented and should be avoided. enter image description here

Use @app.get(...) instead.

from fastapi import FastAPI, Request
app = FastAPI()

@app.get("/{full_path:path}")
async def root(full_path: str, request: Request):
    print(request.method ,full_path)
    return "HIYO"
