RuntimeError: no running event loop

[claudiorrrr]

Hi, with the new version this is not working anymore. When I run server.py and go to the browser, the app shows an error message. This is the output at CLI

I don't know how to sort it out (on MacOS)

Hmm, asyncio event loop is mysterious because it seems changed its behavior recently (months? after legacy cat-printer but before new), and I see some deprecation notes that haven't been there long time ago.

Anyway, let me try if I can sort out with condition... Please wait...

... Hey, why closed 🙃 EDIT: I have sense it's (just) bluetooth not enabled. Is it true? Please say so I can probably add a check to notify users :)

Ha, I closed bc it started working after I reboot :/

Oh, okay 😄
