You can't use the Pythonasyncfunction type for your handler function. Optionally, a handler can return a value, which must be JSON serializable. Common return types includedict,list,str,int,float, andbool. What happens to the returned value depends on theinvocation typeand theservicethat invoke...

The latter has to define .__aenter__() and .__aexit__() rather than .__exit__() and .__enter__(). As you might expect, async with can only be used inside a coroutine function declared with async def.If you’d like to explore a bit more, the companion files for this ...
