Python Object of type WebElement is not JSON serializable

Question

I want convert dict to json using json.dumps but i have problem with WebElement.

I got TypeError: Object of type WebElement is not JSON serializable

This my example code :

def x():
  p = {'a':'a','b':driver.find_element(By.XPATH, xpath)}
  return p
dict = x()
print(json.dumps(dict))

I want convert json except WebElement but without modify x function.

json only knows about standard variable types -- integers, strings, lists, and so on. It can't handle custom classes such as `WebElement`. You can convert the element into a string with `'b': str(element)`. — John Gordon, Jan 25 '21 at 19:00
@JohnGordon but i cant modify to str(element), its a dict from return function — Anas Fanani, Jan 25 '21 at 19:04
What do you mean you can't modify it? You can call `str()` on anything. — John Gordon, Jan 25 '21 at 19:06

Your element object is not serializable. if you can convert the element object to a string. After you can set to b key.

element = str(driver.find_element(By.XPATH, xpath))
dict = {'a':'a','b':element}
print(json.dumps(dict))
