i have a big problem with running selenium script which opens chromium browser and shows some dashboards in Tableau from auto start. I am using Raspberry Pi 4 with newest Raspbian from their webpage.
When performing script manually, everything works fine and as should. I tried tips from several posts for ex. Selenium Script on Startup So i tried various things with my cronos setups: dealays on script run, setting up screen etc. Still nothing helps.
Logger from cronos returns me error like this:
/home/pi/Documents/test.py:22: DeprecationWarning: executable_path has been deprecated, please pass in a Service object
driver = webdriver.Chrome(
Traceback (most recent call last):

(The process started from chrome location /usr/bin/chromium-browser is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
Normally when working good it should stop on and starting to perform Selenium tasks in newly opened chromium browser:
/home/pi/Documents/test.py:22: DeprecationWarning: executable_path has been deprecated, please pass in a Service object
driver = webdriver.Chrome(
Right now after many tries my cronos file looks like:
@reboot sleep 60; env -i DISPLAY=:0.0 python /home/pi/Documents/test.py > /home/pi/logs/cronlog 2>&1
Hope that anybody could help me, i am struggling with this problem from many hours and tried various and many solutions but nothhins seems working.
