import asyncio from arsenic import get_session, browsers, services async def example(): service = services.Geckodriver() browser = browsers.Firefox() async with get_session(service, browser) as session: await session.get('https://example.com') print(await session.get_url()) asyncio.run(example())

Debug

Known issues

breakingarsenic 21.x dropped support for Python 3.6 and earlier. Ensure your environment uses Python 3.7+.

fix

Upgrade to Python 3.7+ or pin to arsenic==20.x

affects: >=21.0

deprecatedThe 'Geckodriver' service now requires passing 'log_file' as a keyword argument (no longer positional).

fix

Use services.Geckodriver(log_file='/path/to/log') instead of positional arg.

affects: >=21.0

gotchaarsenic sessions use asyncio; you must call await on all browser methods. Forgetting leads to coroutine warnings.

fix

Always use await with session methods: await session.get(url), await session.get_page_source()

affects: all
