Selenium 错误：StaleElementReferenceException

问：

如果您看到附加的图像，我需要拨动该开关，因为我不希望这个系统以我的名义运行，而是以系统名称运行。我需要单击此切换开关以切换为系统模式运行。我收到一个错误 StaleElementReferenceException，当我做一些研究时，我需要导入 NoSuchElementException 和 StaleElementReferenceException 并将其分配给igonered_exception然后调用此变量在 run_as_button 变量的 webdriverwait 函数中初始化它......当我这样做时，我仍然收到错误。

您将在下面找到 python 中的相关代码，其中包括导致此错误的导入和代码行

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait, Select
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import StaleElementReferenceException
from selenium.webdriver.support import expected_conditions as EC

#ignore exception
igonered_exception = (NoSuchElementException, StaleElementReferenceException)

#run as system
run_as_button = WebDriverWait(driver,120,ignored_exceptions=igonered_exception).until(EC.element_to_be_clickable((By.XPATH,('//*[@id="core-page main"]/div[2]/div/lp-section/section/div/div/div[2]/div[3]/lp-slide-toggle/div'))))
action.move_to_element(run_as_button).click(run_as_button).perform()

下面是拨动开关的 HTML 代码的截图

   <div _ngcontent-qyq-c18="" class="col col-md-3"></div>
   <div _ngcontent-qyq-c18="" class="col-12 col-md-2 d-flex align-items-center"><label _ngcontent-qyq-c18="">Run as System</label></div>
