File doesn't download in headless chrome

[rishabhsiitk]

I am using docker image public.ecr.aws/sam/build-python3.7 with following configuration
selenium==4.0.0a5
urllib3==1.26.6
https://github.com/adieuadieu/serverless-chrome/releases/download/v1.0.0-37/stable-headless-chromium-amazonlinux-2017-03.zip
https://chromedriver.storage.googleapis.com/2.37/chromedriver_linux64.zip

and below is the code

from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service

opts = Options()
opts.binary_location = '/opt/headless-chromium'
opts.add_argument("--headless")
opts.add_argument('--no-sandbox')
opts.add_argument("−−incognito")
opts.add_argument("--disable-dev-shm-usage")
opts.add_argument("--single-process")
opts.add_argument('--start-maximized')
opts.add_argument('--start-fullscreen')
opts.add_argument("--window-size=1499x2200")
opts.add_experimental_option('prefs', {
"download.default_directory": '/tmp',
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"plugins.always_open_pdf_externally": True
})

svc = Service(executable_path='/opt/chromedriver')
browser = Chrome(service=svc, options=opts)

# any file/pdf download link, giving a sample
browser.get("http://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32016R0679")

file is not being download neither in /tmp(passed as default download directory) nor anywhere.
Can someone guide/help with this issue?

In local chrome on your computer, you can download file with this code?

Yeah, i am able to download it on my local but i am not using headless-chrome instead the local chrome with below code

opts = Options()
opts.add_argument("--headless")
opts.add_argument("−−incognito")
opts.add_experimental_option('prefs', {
"download.default_directory": os.getcwd(),
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"plugins.always_open_pdf_externally": True
})
browser = Chrome(options=opts)

how about trying local again WITH the options? The diffs between envs should be minimized to debug.

Also, you can try my repository instead of using this repository. It may work if this headless chrome is broken some how. the version of headless chrome is really old nowadays.

@umihico on my local, it's working with below option

opts = Options()
opts.add_argument("--headless")
opts.add_argument('--no-sandbox')
opts.add_argument("−−incognito")
opts.add_argument("--disable-dev-shm-usage")
opts.add_argument("--single-process")
opts.add_argument('--start-maximized')
opts.add_argument('--start-fullscreen')
opts.add_argument("--window-size=1499x2200")
opts.add_experimental_option('prefs', {
"download.default_directory": os.getcwd(),
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"plugins.always_open_pdf_externally": True
})
browser = Chrome(options=opts)
