find_element_by_xpath().click() method

[Zhang Zhao]

I was trying to click a tab on a Salesforce org by find_element_by_xpath().click() method. I verified that the xpath on Chrome and it was able to locate the element. However the script failed with error below when it was clicking the element:

Traceback (most recent call last): File "/Users/zhangzhao/PycharmProjects/selenium/crm-sla.py", line 17, in <module> browser.find_element_by_xpath('//one-app-nav-bar-item-root[@data-id="0KD5f000001Jh2QGAS"]/a').click() File "/Users/zhangzhao/PycharmProjects/selenium/venv/lib/python3.9/site-packages/selenium/webdriver/remote/webelement.py", line 80, in click self._execute(Command.CLICK_ELEMENT) File "/Users/zhangzhao/PycharmProjects/selenium/venv/lib/python3.9/site-packages/selenium/webdriver/remote/webelement.py", line 633, in _execute return self._parent.execute(command, params) File "/Users/zhangzhao/PycharmProjects/selenium/venv/lib/python3.9/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute self.error_handler.check_response(response) File "/Users/zhangzhao/PycharmProjects/selenium/venv/lib/python3.9/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.JavascriptException: Message: javascript error: Cannot read properties of undefined (reading 'defaultView') (Session info: chrome=101.0.4951.41)

For debugging purposes, I added an assertion for that element instead of click() and the script worked as expected. Anyone can gimme some hints why I was getting the error? Is it sth. with the click() method? Below is my script.

from selenium import webdriver 

baseUrl = "https://login.salesforce.com/" 

username = "xxx" 

password = "xxx" 

accountName = "Aaa Aaa"

browser = webdriver.Chrome()

browser.get(baseUrl)

browser.find_element_by_id("username").send_keys(username)

browser.find_element_by_id("password").send_keys(password)

browser.find_element_by_id("Login").click()

browser.implicitly_wait(20)

browser.find_element_by_xpath('//one-app-nav-bar-item-root[@data-id="0KD5f000001Jh2QGAS"]/a').click() 

browser.implicitly_wait(10)

# Add assertion to verify if text is present

# element = browser.find_element_by_xpath('//one-app-nav-bar-item-root[@data-id="0KD5f000001Jh2QGAS"]/a/span').text 

# assert element == "My Account", "element was not found..." 

browser.quit()
