**Selenium and Chrome verions:**

import selenium
selenium.__version__
'4.10.0'

Chrome Version: 114.0.5735.91 (Official Build) (64-bit)

**This code used to work for me just fine:**
```python
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By

My_Link = "......"

DRIVER_PATH = 'I://Decoded//chromedriver.exe'
s=Service(DRIVER_PATH)
browser = webdriver.Chrome(service=s)

browser.get(My_Link)
browser.find_element(By.NAME,"USER").send_keys(r)
browser.find_element(By.NAME,"PASSWORD").send_keys(d)
browser.find_element(By.CSS_SELECTOR,".ButtonSm").click()

cookies= browser.get_cookies()

It's now giving me this error:

WebDriverException                        Traceback (most recent call last)
<ipython-input-10-b6bb484d2c6a> in <module>
      1 
      2 
----> 3 cookies= browser.get_cookies()

WebDriverException: Message: unknown error: Runtime.callFunctionOn threw exception: TypeError: JSON.stringify is not a function
    at buildError (<anonymous>:323:18)
  (Session info: chrome=114.0.5735.91)
Stacktrace:
Backtrace:
    GetHandleVerifier [0x010CA813+48355]
    (No symbol) [0x0105C4B1]

Any idea what is causing this exception pls ?

# 答案1
**得分**: 1

由于您正在使用Selenium版本`v4.10.0`，设置`driver.exe`路径是可选的。您可以将下面的代码替换为：

```python
browser = webdriver.Chrome()

参考 - https://stackoverflow.com/a/76463081/7598774

DRIVER_PATH = 'I://Decoded//chromedriver.exe'
s=Service(DRIVER_PATH)
browser = webdriver.Chrome(service=s)

browser = webdriver.Chrome()

WebDriverException: Message: unknown error: Runtime.callFunctionOn threw exception: TypeError: JSON.stringify is not a function

这个错误消息是由于ChromeDriver二进制文件的最近更改引起的回归问题。

这个问题在org.openqa.selenium.WebDriverException: unknown error: Runtime.callFunctionOn threw exception: TypeError: value.hasOwnProperty is not a function at Object.stringify线程中讨论，并且这个问题需要在ChromeDriver中修复。

tl; dr
使用Selenium和ChromeDriver时，出现WebDriverException: unknown error: Runtime.callFunctionOn threw exception: TypeError: JSON.stringify is not a function。

WebDriverException: Message: unknown error: Runtime.callFunctionOn threw exception: TypeError: JSON.stringify is not a function
