I think the most robust fix is to change the user agent to firefox, which is actually the browser used with playwright and to update the version the one used by playwright. Hence, when playwright is outdated, the login will fail. Once playwright is updated, the USER_AGENT "constant" will update alongside.
I agree with the above comment, but if the website does not want to load correctly in firefox for some reason the below library could be used to get a "popular" user agent each time it is called. This should accomplish the same thing.
Yes, that was my first thought. However, this schwab-API currently hardcoded firefox anyways. If anything else entered in SessionManager.browserType, it defaults to webkit, which actually doesn't work with Schwab. At least not on the two machines I tried it on. Additionally:
I've made a simple tweak to authenticate.py and tested it. I works now and I am about to create a pull request. Until this change is approved, I recommend adding the following line to your code right after the api call:
api = Schwab()
version = api.browser.version usr_agent = f"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:{version}) Gecko/20100101 Firefox/{version}" api.page = api.browser.new_page( user_agent = usr_agent, viewport = { 'width': 1920, 'height': 1080 } )
I believe your solution is best then for sure. Very simple. I just went into site packages and hardcoded a Firefox user agent to v123.00 and it worked fine for me as well. If it does not get approved, I will use the above.
Out on vacation, but I've approved the change. Will try to identify a more robust solution to this type of thing going forward
Not sure if this is still relevant, but I had another workaround for this. This is what I implemented while experimenting with the Playwright async API:
try:
async with self.page.expect_navigation():
await self.page.frame(name=login_frame).press("[placeholder=\"Password\"]", "Enter")
except TimeoutError:
raise Exception("Login was not successful; please check username and password")
# Handles out-of-date user agent
if await self.page.get_by_text("Time to Update Your Browser").is_visible():
async with self.page.expect_navigation():
await self.page.click("button:text(\"Continue\")")
if self.page.url != urls.trade_ticket():
return False
await self.page.wait_for_selector("#_txtSymbol")
If you think something like this would be useful, and sufficiently robust, I can raise a PR once https://github.com/itsjafer/schwab-api/pull/51/files has been merged.
It seems the user-agent passed along with the playwright identification is causing this page to show up, which in turn causes the identification to fail as of this morning.
A quick fix would be to update the user-agent string, however, a more robust solution is needed.
