TypeError: Objekt vom Typ Relativeby ist nicht json serialisierbar mit Find_elements mit relativen Locators ⇐ Python

[Anonymous]

Warum erhalte ich den Fehler unten, wenn die Methode Signatur von find_elements () anscheinend Relativeby unterstützt? Ich habe diesen Fehler umgangen, indem ich RelativeBy nicht verwendet habe.

Code: Select all

    inner_elements = element.find_elements(by, value)

< /code>
Ich habe einen relativen Wert verwendet, um in einem bestimmten Element ein Element zu finden.myRelativeLocator = locate_with(By.CSS_SELECTOR, "div.someclass").below({By.CSS_SELECTOR:"h4.some_label"})
myWebsitePopupWindow.find_elements(myRelativeLocator)
< /code>
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.relative_locator import locate_with

domain = "https://www.lazyvim.org/"
driver = webdriver.Chrome(webdriver.ChromeOptions())
driver.maximize_window()

driver.get(domain)

# sleep to view result for debugging purpose. not required
time.sleep(3)

# i know implicit wait are bad.  just for demo code
driver.implicitly_wait(3)

# find the sidebar on left
sidebar_selector = (By.CSS_SELECTOR, "div.sidebar_njMd")
sidebar = driver.find_element(*sidebar_selector)

# find the > button next to configuration side  menu to expand content
config_dropdown_button_selector = locate_with(
By.CSS_SELECTOR, "button.clean-btn.menu__caret"
).straight_right_of({By.CSS_SELECTOR: 'a[href="configuration"]'})
config_dropdown_button = sidebar.find_element(config_dropdown_button_selector)

# click the > button
config_dropdown_button.click()
