TypeError: object NoneType can't be used in 'await' expression

Trying to run example with async repeat_at function.

from fastapi import FastAPI
from contextlib import asynccontextmanager
from fastapi_utilities import repeat_every, repeat_at

@asynccontextmanager
async def lifespan(app: FastAPI):
    # --- startup ---
    await test()
    await test2()  # ------------- await added here
    yield
    # --- shutdown ---

app = FastAPI(lifespan=lifespan)

# Repeat Every Example
@repeat_every(seconds=2)
async def test():
    print("test")

# Repeat At Example
@repeat_at(cron="* * * * *")
async def test2():  # ------------- async added here
    print("test2")

After executing command fastapi dev main.py I got this error:

INFO:     Waiting for application startup.
ERROR:    Traceback (most recent call last):
