Setting an additional log handler to the uvicorn logger for access logs in fastapi was not straightforward, but This post was very helpful.


```
@app.on_event("startup")
async def startup_event():
    logger = logging.getLogger("uvicorn.access")
    handler = logging.StreamHandler()
    handler.setFormatter(logging.Formatter("%(asctime)s - %(levelname)s - %(message)s"))
    logger.addHandler(handler)
```
