Detected blocking call to open with args

[Eigeplackter]

Hi,

as I have no idea of this code, I thought Id drop the issue in here.
I see an issue with HA Core, but not sure if thats the same problem:

Same here, I'm on the latest HA version and still receive this error in my log

Same here, I get this error from the pyscript 1.6.1 integration running the latest HA 2025.1.0:

2025-01-04 23:24:36.082 WARNING (MainThread) [homeassistant.util.loop] Detected blocking call to open with args ('/usr/local/lib/python3.13/site-packages/pytz/zoneinfo/Africa/Abidjan', 'rb') inside the event loop by custom integration 'pyscript' at custom_components/pyscript/eval.py, line 1982: return func(*args, **kwargs) (offender: /usr/local/lib/python3.13/site-packages/pytz/__init__.py, line 108: return open(filename, 'rb')), please create a bug report at https://github.com/custom-components/pyscript/issues

I don't think it actually creates a problem right now, but of course I'd prefer not to have it in my logs. Any suggestion if there is anything I can do about it?
