This short trivial code worked fine as of bef. yesterday, but now send_keys is not working anymore:

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://www.google.com")
elem = driver.find_element_by_name("q")
elem.send_keys("Hello WebDriver!")
elem.submit()
print(driver.title)

This is the stack trace:

C:\Users\Rui\PycharmProjects\geo\venv\Scripts\python.exe C:/Users/Rui/PycharmProjects/geo/send_keys.py
debug value ('Hello WebDriver!',)
Traceback (most recent call last):
  File "C:/Users/Rui/PycharmProjects/geo/send_keys.py", line 5, in <module>
    elem.send_keys("Hello WebDriver!")
  File "C:\Users\Rui\PycharmProjects\geo\venv\lib\site-packages\selenium\webdriver\remote\webelement.py", line 483, in send_keys
    'value': keys_to_typing(value)})
  File "C:\Users\Rui\PycharmProjects\geo\venv\lib\site-packages\selenium\webdriver\remote\webelement.py", line 632, in _execute
    return self._parent.execute(command, params)
  File "C:\Users\Rui\PycharmProjects\geo\venv\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 312, in execute
    self.error_handler.check_response(response)
  File "C:\Users\Rui\PycharmProjects\geo\venv\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: call function result missing 'value'
  (Session info: chrome=65.0.3325.181)
  (Driver info: chromedriver=2.34.522940 (1a76f96f66e3ca7b8e57d503b4dd3bccfba87af1),platform=Windows NT

6.1.7601 SP1 x86)

Process finished with exit code 1

(the string:

debug value ('Hello WebDriver!',)

results that trying to understang what is going on, in "webelement.py" I added this line "print("debug value " + str(value))":

def send_keys(self, *value):
    # 2018MAR25
    # send_key generating errors since 2018MAR24!
    print("debug value " + str(value))

And as it really prints "debug value ('Hello WebDriver!',)" I cannot understand why "webelement.py" is complaining that "call function result missing 'value'"

Can someone enlighten me? How can i solve this issue? I noticed that Chrome was updated to 65 around this date, could it be related?

Windows 7 32 bit

Selenium 3.11.0

Python 3.6.4

Your chrome driver seems not latest. if you are using chrome 65 then you need latest chrome driver.

Please take latest version of chrome driver from here : https://chromedriver.storage.googleapis.com/index.html?path=2.37/

It should resolve your sendkey issue.
