Selenium: Chrome failed to start: exited abnormally

Question

I’m trying to make an application with python and selenium but I run into an error.
I already searched for a solution and found out that you should add those arguments: --no-sandbox, --headless, --disable-dev-shm-usage which I did but it still didn’t work. The error (full traceback below): selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally.

This happens on the initialization of the driver.

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--no-sandbox')
options.add_argument('--headless')
options.add_argument('--disable-dev-shm-usage')

driver = webdriver.Chrome("/usr/bin/chromedriver", options=options)

Edit

In addition to this code it’s hosting a flask app for a website which runs with uwsgi and nginx. I noticed when I run the script, it works. However it doesn’t when I run it as a service with uwsgi.

myapp.ini

[uwsgi]
module = wsgi:app

master = true
processes = 5

socket = myapp.sock
chmod-socket = 660
vacuum = true

die-on-term = true

logto = /var/log/uwsgi/%n.log

Add :/usr/bin:/bin to your PATH as shown below:

Environment="PATH=/home/admini/websites/myapp/venv/bin:/usr/bin:/bin"

Complete file looks like this:
