Python selenium webdriver throws unicode Attributes errors

[sri85]

We are using python selenium webdriver , of late we see error like <type 'exceptions.AttributeError'>, AttributeError("'unicode' object has no attribute 'text'",), <traceback object at 0x0000000003434C48>) .

We are using 2.45 version of selenium python version 2.7.7 .

And also we see this problem intermittently ? Is it a known issue , when i dug into source code of webdriver.py it has a line str= basestring which should fix most of the unicode errors. Since it happens intermittently its hard to provide more logs

[lukeis]

please provide a full traceback of the error and sample code to attempt to reproduce this. As it stands there's nothing anyone can do to even look into your issue. We can reopen this when something more is provided.

Also for generic user help / questions. Please ask on the selenium-users mailing list:
https://groups.google.com/forum/#!forum/selenium-users

@lukeis Stacktrace , this is what i got , hope this helps

Could you reopen this issue now?

[lukeis]

the stacktrace is a good start... can you provide some code to attempt to reproduce this on our side? Seems that there's more in play here than you're letting on originally, you appear to be using the event firing webdriver too.

Below is code snippet that i have in my framework:
So basically i have implemented cusomt wait methods and then i am monkey patching the driver to be able to use these custom methods

class WebDriverExtensions(object):
    def wait_until(self, func, timeout, timeout_message):
        """

        :type self: selenium.webdriver.remote.webdriver.WebDriver
        """
        WebDriverWait(self, timeout).until(
            lambda method: func(), timeout_message)
        return self


    @staticmethod
    def patch(driver):
        """

        :type driver: selenium.webdriver.remote.webdriver.WebDriver
        """
        driver.wait_until = WebDriverExtensions().wait_until
        driver.wait = PSWait(driver)
        return driver

class PSWait(object):
    def __init__(self, driver):
        self.driver = driver

    def _wait_until_visible(self, locator, timeout, message, is_visible):
        if message is None:
            message = "Could not find {} in {} seconds".format(str(locator), timeout)

        wait = WebDriverWait(self.driver, timeout)
        if is_visible:
            wait.until(EC.visibility_of_element_located(locator), message=message)
        else:
            wait.until(EC.invisibility_of_element_located(locator), message=message)

    def until_visible(self, locator, timeout=3, message=None):
        self._wait_until_visible(locator, timeout, message, True)

    def until_not_visible(self, locator, timeout=3, message=None):
        self._wait_until_visible(locator, timeout, message, False)

driver = WebDriverExtensions.patch(driver)
        driver = EventFiringWebDriver(driver, DefaultWebDriverEventListener(logger))
return driver

class DefaultWebDriverEventListener(AbstractEventListener):
    logger = None

    def __init__(self, logger):
        self.logger = logger

    def on_exception(self, exception, driver):
        self.logger.info("Exception raised: " + str(exception))

    def before_click(self, element, driver):
        self.logger.info("Clicking element")

    def before_find(self, by, value, driver):
        self.logger.info("Locating element by " + str(by) + " " + str(value))

Some of the elements which throw this error are , hope this helps
By.XPATH, "//a[@class='company-logo']"
self.driver.find_element(By.XPATH, "(//div[@class='browse-data-entry']/h3)[{}]".format(index)).text

And also could you reopen the issue

[lukeis]

I just tried to reproduce with your code provided and i don't know what DefaultWebDriverEventListener is:

https://gist.github.com/lukeis/b30520ada6c27e58c31e

[sri85]

I have updated the code for DefaultWebDriverEventListener

[lukeis]

I've updated my gist:
https://gist.github.com/lukeis/b30520ada6c27e58c31e

Can't reproduce the issue, tried running a few times.

[sri85]

Thanks for trying 👍

[sri85]

As I said it isn't reproducible 100% , happens intermittently

[sri85]

I found out the root cause of the bug , one of the test was calling the driver.quit and our framework in its teardown class was trying to access the driver object , that's the reason it was throwing error
