the function should be async

[PieroValdebenito]

Example

Wrong ❌

@app.get("/")
cache(expire=30)
def healcheck():
    return {'status': 'OK'}

Good ✅

@app.get("/")
cache(expire=30)
async def healcheck():
    return {'status': 'OK'}

According to the official documentation of fastapi,
functions can (and should) be synchronous if necessary. (E.g. for interacting with DB)
https://fastapi.tiangolo.com/async/#in-a-hurry

the workaround is simple check asyncio.iscoroutinefunction(func)..

[long2ice]

Because we use aioredis, aiobotocore inside etc.
