I'm running some stuff that necessitates browser automation on an AWS instance. I'm trying to run Selenium with a virtual display, but my code crashes whenever I try to use Selenium to send keyboard input to a page. I can download source code and locate elements on pages, but not use the send_keys method. Below is an MWE reproducing the crash:
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1920, 1080))
display.start()
driver = webdriver.Chrome()
driver.get("http://google.com")
search_field = driver.find_element_by_id("lst-ib")
search_field.send_keys("foo")
And here's a stacktrace:
Traceback (most recent call last):
File "mwe.py", line 12, in <module>

My Google Fu has failed me thus far, so any input is highly appreciated.
