Exception: No "request" or "websocket" argument on function

[huths0lo]

Describe the bug
If the rate limiter is not specifically instantiated as "limiter", it throws this error when adding an endpoint with the rate limiter decorator:
Exception: No "request" or "websocket" argument on function

To Reproduce
rate_limiter = Limiter(key_func=get_remote_address)
app.state.limiter = rate_limiter
app.add_exception_handler(RateLimitExceeded, _rate_limit_exceeded_handler)

@app.get("/home")
@rate_limiter .limit("5/minute")
async def homepage(request: Request):
return {
"message": "Hello world",
}

Expected behavior
The object should function regardless of what variable it is instantiated under.

Hey @huths0lo, I ran into the same problem. I solved it by adding a Request object to the param of the function:

Example Below:

from fastapi import APIRouter, Request
from routers.limiter import limiter

health_check = APIRouter(
    prefix="/health",
    tags=["Health Check"]
)

@health_check.get("/")
@limiter.limit('1/second')
async def health_check(request: Request):
    return {"message": "Server is running :) !"}
