  • This error message...

    invalid selector: Unable to locate an element with the xpath expression //div[contains(., 'Medium') because of the following error:
SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//div[contains(., 'Medium')' is not a valid XPath expression.

    IWebElement element = driver.FindElement(By.XPath("//div[contains(., 'Medium')]"));
