2022-07-17 01:51:31 UTC - Matt Welke: Does the Python runtime support async/await syntax via asyncio? I made a Python 3.10 version of the runtime, based on code in the repo openwhisk-runtime-python. I deployed an action based on it and it works fine if I use `def main(args):` in my action:
```{
  "greeting": "Hello stranger! 1 + 2 = 3. Here's a joke: An SEO expert walks into a bar, bars, pub, public house, Irish pub, tavern, bartender, beer, liquor, wine, alcohol, spirits...",
  "python_version": "3.10.5 (main, Jul 12 2022, 11:43:42) [GCC 8.3.0]"
}```
But doesn't work if I use `async def main(args):` (and I have `import asyncio` at the top of the file):
```{
  "code": "d7cf54b866121a2b5937a184bfae2640",
  "error": "There was an error processing your request."
}```
I also get a more detailed error message in the IBM Cloud Function logs:
