I have been using selenium now for a while on a number of projects.

With code that was running I am now receiving the following error:   

C:\Users\%USER%\Miniconda\python.exe C:/Users/%USER%/PycharmProjects/c_r/

  Traceback (most recent call last):

      File "C:/Users/%USER%/PycharmProjects/c_r/", line 17, in <module>


      File "C:\Users\%USER%\PycharmProjects\c_r\", line 40, in setUp

        self.driver = webdriver.Chrome()

      File "C:\Users\%USER%\Miniconda\lib\site-packages\selenium\webdriver\chrome\", line 67, in __init__


      File "C:\Users\%USER%\Miniconda\lib\site-packages\selenium\webdriver\remote\", line 87, in __init__

        self.start_session(desired_capabilities, browser_profile)

      File "C:\Users\%USER%\Miniconda\lib\site-packages\selenium\webdriver\remote\", line 141, in start_session

        'desiredCapabilities': desired_capabilities,

      File "C:\Users\%USER%\Miniconda\lib\site-packages\selenium\webdriver\remote\", line 201, in execute


      File "C:\Users\%USER%\Miniconda\lib\site-packages\selenium\webdriver\remote\", line 181, in check_response

        raise exception_class(message, screen, stacktrace)

    selenium.common.exceptions.WebDriverException: Message: unknown error: unrecognized Blink revision: 3b3c00f2d95c45cca18ab944acced413fb759311

      (Driver info: chromedriver=2.10.267521,platform=Windows NT 6.3 x86_64)

    Process finished with exit code 1

where c.setUp() is:

def setUp(self):

   self.driver = webdriver.Chrome()

Again - this is code that WAS running and I am unsure how to this "Unrecognized blink revision" error.

Nothing has consciously changed.

Thank you for any pointers

I think that this basically is a compatibility issue between ChromeDriver and Chrome browser. I suspect your Chrome auto-updated itself and is basically too new for the ChromeDriver version you currently have. I suggest you  update ChromeDriver, currently, the latest version is ChromeDriver 76.0.3809.68
