Is it possible to change the tag manager environment programmatically (Selenium/Python?)

[mpeabody7]

I can change the environment by opening the Adobe Experience Platform Debugger extension, clicking Experience Platform Tags, clicking Configuration, clicking Actions, and selecting Replace, but I need to be able to do this programmatically for automated testing.

This is in the head of the webpage (unique data replaced with ellipsis):

<script src="//assets.adobedtm.com/.../launch-....min.js" async></script>

Am I able to change the source to a different URL using Selenium/Selenium-wire and Python?

Hey @mpeabody7 

Try the below script. Should work for you. 

from selenium import webdriver

# Initialize the WebDriver (You should have the appropriate driver installed)
driver = webdriver.Chrome()

# Navigate to a webpage
driver.get("https://example.com")

# Find the script element by CSS selector or XPath (change this selector as needed)
script_element = driver.find_element_by_css_selector("script[src='original_script.js']")

# Replace the src attribute with the new script URL
new_script_url = "https://new_script.js"
driver.execute_script(f"arguments[0].src='{new_script_url}'", script_element)

# Optionally, you can trigger script execution if needed
# driver.execute_script("arguments[0].parentNode.removeChild(arguments[0])", script_element)
# driver.execute_script("document.head.appendChild(arguments[0])", script_element)

# Close the WebDriver session
driver.quit()

Let me know if you face issues.

I'm trying this code, which uses the newer syntax:

    try:
        script_element = WebDriverWait(browser, 25).until(
            EC.presence_of_element_located((By.CSS_SELECTOR, "script[src*='assets.adobedtm.com']"))
        )
        new_script_url = "https://assets.adobedtm.com/asdf1234/asdf1234/launch-asdf1234-development.min.js"
        browser.execute_script(f"arguments[0].src='{new_script_url}'", script_element)

    except NoSuchElementException:
        print('Cannot find script')

But it's not finding it (trying to match the substring of 'assets.adobetm.com'). I'm wondering if it's because that script exists in the head of the page.

Hey @mpeabody7 

The script being in the head would not impact the execution. It should work. Might be a timing issue. Does the DOM load completely before the script executes ?

Let me try it at my end as well and see what I get.

Cheers.
