I have been successfully testing this piece of python3 code to automate a login process via helium, on my macbook
from helium import *
browser = start_chrome('https://example.com/sign_in')
wait_until(Text("Sign In").exists)
write('example@gmail.com', into='email')
write('example', into='password')
click(S(".icheckbox"))
time.sleep(5)
click("Sign in")
time.sleep(10)
click("Home")
go_to("https://example.com/appointment")
content = get_driver().find_element_by_tag_name('pre').text
print(content)
kill_browser()
It works as intended. When I run it on the terminal, it opens up chrome and follows the instructions. But when I try to run the same code on my centos8 vps server(i have installed exactly the same chrome version and helium version) I encounter a problem.
raise RuntimeError(self.DRIVER_REQUIRED_MESSAGE)
RuntimeError: This operation requires a browser window. Please call one of the following functions first:
I try running the same code with -headless parameter
options.add_argument('--no-sandbox')
options.add_argument('headless')
options.add_argument("--disable-extensions")
options.add_argument("--start-maximized")
options.add_argument("window-size=1400,600")
browser = start_chrome("https://example.com", options=options)
It doesn't log in at all. At the moment I remove headless and sandbox
options = ChromeOptions()
options.add_argument("--disable-extensions")
options.add_argument("--start-maximized")
options.add_argument("window-size=1400,600")
browser = start_chrome("https://example.com/sign_in", options=options)
I get
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
I was thinking maybe I should install desktop version of centos on my vps? Has anyone encountered this scenario before, if so what was the solution you went with?
Thank you
