Describe the bug
This error happens in some specific situations, usually when directly or indirectly opening a pdf preview page.
def test():
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=False) _**#In this situation, with headless set to False, the blank pdf is issued, but when set to True, it is not possible to send it. Any suggestion?**_
context = browser.new_context()
page = context.new_page()
page.goto('https://nyc3.digitaloceanspaces.com/midia/wp-content/uploads/2023/01/4tmrioel-sample.pdf')
page.pdf(path='Test.pdf', format='A4')
test()
For example, in the code snippet below, the pdf is generated empty, blank (the screenshots are black with no content). I noticed that this error happened because of the speed, so I used the sleep library, as wait_for_load_state() does not work in this case. However, the new generated pdfs come out with the wrong formatting (here is an attached image showing a print, I hid the content, but the layout is the same withou the black)
My theory is that the page generates like this because of the chromium pdf viewer summary. So, I tried to disable it in this code:
def test():
from playwright.sync_api import sync_playwright
from time import sleep
with sync_playwright() as p:
# browser = p.chromium.launch(headless=False)
browser = p.chromium.launch_persistent_context(user_data_dir=r'C:\Users\pedro\AppData\Local\Temp\playwright_chromiumdev_profile-AidV4Q\Default', args=['--print-to-pdf', '--disable-extensions', '--print-to-pdf-no-header'], headless=False)
page = browser.new_page()
page.goto('https://nyc3.digitaloceanspaces.com/midia/wp-content/uploads/2023/01/4tmrioel-sample.pdf')
sleep(5)
page.pdf(path='test.pdf', format='A4')
input()
Still, I couldn't solve the problem. Details: Unable to run these codes in Headless mode, chromium appears to be being automated (making detection easier). So, does anyone have a solution to my problem?
