Timeout and missing element with playwright local

[SamuelBuhan]

Hi,

I was wondering if you know more about this bug I have. I use "local" playwright fetch_mode due to token issue and try to execute:
result: Result = get_flights( flight_data=[ FlightData(date="2025-03-01", from_airport="MHT", to_airport="CDG") ], trip="one-way", seat="economy", passengers=Passengers(adults=2, children=1, infants_in_seat=0, infants_on_lap=0), fetch_mode="local", )

The result is:
`Traceback (most recent call last):

Any thoughts on this?

Hi @SamuelBuhan! I'm Dosu and I’m helping the flights team.

The timeout is happening because the Playwright script is waiting for the selector .eQ35Ce, which Google Flights no longer uses. This was fixed in the project by switching to wait for [role="main"] instead, and by using wait_until="networkidle" to ensure the page is fully loaded before scraping. You’ll want to update your fast-flights package to the latest version to get this fix, or update your local code to wait for [role="main"] instead of .eQ35Ce in the Playwright script cite.

For the 401 "no token provided" error, that's related to the remote fallback mode, not local mode. The library now embeds a default consent cookie bundle to bypass Google's consent page, but you can override this by passing your own cookies or setting cookie_consent=False if you need custom authentication cite.

Make sure you’ve installed Playwright and the Chromium browser as described in the docs. If you still see issues after updating, try running Playwright in non-headless mode for debugging, or explicitly provide cookies if you suspect authentication problems.

To reply, just mention @dosu.
