I'm trying to submit some requests on a web page from my web application. Because that web page is rather complex I decided not to send HTTP requests directly but rather use Selenium. I've deployed Selenium, firefox and geckodriver. All of that is running on a virtual Ubuntu.
geckodriver is located in bin folder of web app's venv:
-rwxr-xr-x 1 ralfeus ralfeus 7.0M Jul 28 23:45 bin/geckodriver*
The code to run it is here:
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.firefox.options import Options
options = Options()
options.set_headless(headless=True)
browser = webdriver.Firefox(firefox_options=options)
When I run a script directly from a shell everything works fine. I can create an instance of webdriver, can open a page.
uWSGI application runs as 'www-data' user When I run it as a part of uWSGI I'm getting an error:

As same code works fine from a shell, I've ruled out path and binaries issues. What else could it be?
