Python Code Tool - Web Scraping Dynamic Websites Using Selenium

6 - Meteoroid

Hi David,


Thank you for this post, I have been able to use the information you presented here to set up some workflows that successfully pull daily numbers from a few different public health websites for COVID-19 tracking. My question is about scheduling these workflows on Alteryx server. Since the web driver (chromedriver, in my case) has to be in an "executable path", how is that set up on the server? Should an Alteryx server admin be able to install a web driver in an executable path accessible to just the server? 


Thanks again!


Hi @bwiegert ,


Yeah pretty much. The setup on the Server will be the same or similar on your machine.


I would just suggest that you align with the admin on what path to put the EXE in. 


Could even be a shared drive with UNC location I think. 


That way, when you push the WF to Server the code would not have to get change to find the resource of the chromedriver on Server env.

First of all thanks for the guide it is very useful,

After some time trying to execute the code and after solving some problems I got stuck in the following:


# Start the WebDriver and load the page

wd = webdriver.Chrome("C:/Users/*****/AppData/Local/Alteryx/bin/Plugins/chromedriver")

print("after ")

# Enter URL you want to scrape



When I execute the code, the browser will appear, but in the address it says "data ;," and it does nothing else, executing the code with the print command, it only executes the print "before".

When i close the browser that message apears:

SessionNotCreatedException                Traceback (most recent call last)

---> 13 wd = webdriver.Chrome("C:/Users/*******/AppData/Local/Alteryx/bin/Plugins/chromedriver")
     14 # Enter URL you want to scrape
     15 wd.get("")

I don't know if it could help me.

Thank you very much and greetings.

I placed the chromedriver in system32 folder and explicitly indicate chromedriver.exe.

This worked when i tested.


from ayx import Alteryx

from import WebDriverWait
from selenium import webdriver

# Start the WebDriver and load the page
# Using Chromium Driver here, need to change path to match youe env
options = webdriver.ChromeOptions();

driver = webdriver.Chrome(options=options,executable_path="C:\\Windows\\System32\\chromedriver.exe")

# Enter URL you want to scrape

I am having same issue. Works on desktop but when I want to schedule at the server, throwing lots of errors.

Thank you for your sharing!


I am able to create a workflow that extract data from the website. I am able to run it manually but it fails when I schedule the job. Image below shows the error. I would love to hear for some advice. Thank you!

Same exact problem: chromedriver crashes.
