### Related Issues
1. exception from python 3.10:
```
TypeError: As of 3.10, the *loop* parameter was removed from Queue() since it is no longer necessary`
```
Remove the deprecated argument `loop` from `Queue`, which can also be omitted in python version < 3.10
2. exception from Sanic > 21.3:
```
File "C:\Users\Kevin\AppData\Local\Temp\zeit-fun-03f18b2d2c7d7\sanic\signals.py", line 93, in get
group, param_basket = self.find_route(
TypeError: 'NoneType' object is not callable
```
As of Sanic > 21.3, it cannot serve requests immediately after initializing, instead, we need implement the [ASGI lifespan protocol](https://asgi.readthedocs.io/en/latest/specs/lifespan.html) and wait for the startup event completed.
here I complemented the protocol copied from (same source of the previous HTTP procotol): <https://github.com/jordaneremieff/mangum/blob/main/mangum/protocols/lifespan.py>
