RuntimeError: Event loop is closed at end of execution in Magentic One Ubuntu 24

[ghosert]

What happened?

I followed the doc to setup everything for Magentic One and run it with this sample:

╭─  gmk-ubuntu   ~/autogen/python/packages/autogen-magentic-one
╰─ python examples/example.py --logs_dir ./my_logs

it works well but in the end of the session, it reports this error:

No agent selected.
