Selenium WebDriverException: unknown error: call function result missing 'value' while calling sendkeys method

问题

When trying to call Sendkeys method in selenium webdriver it is displaying below error:

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value'  
 (Session info: chrome=65.0.3325.146)  
 (Driver info: chromedriver=2.27.440174 (e97a722caafc2d3a8b807ee115bfb307f7d2cfd9),platform=Windows NT 6.1.7600 x86_64) (WARNING: The server did not provide any stacktrace information)

Selenium Jarversion: 3.10.0

The error says it all :

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value'
(Session info: chrome=65.0.3325.146)
(Driver info: chromedriver=2.27.440174 (e97a722caafc2d3a8b807ee115bfb307f7d2cfd9),platform=Windows NT 6.1.7600 x86_64) 

Your main issue is the version compatibility between the binaries you are using as follows :

• You are using chromedriver=2.27
• Release Notes of chromedriver=2.27 clearly mentions the following :

Supports Chrome v54-56

• You are using chrome=65.0
• Release Notes of ChromeDriver v2.36 clearly mentions the following :

Supports Chrome v65-66

• Your Selenium Client version is 3.10.0.
• Your JDK version is unknown to us.

So there is a clear mismatch between the ChromeDriver version (v2.27) and the Chrome Browser version (v65.0)

Solution

• Upgrade ChromeDriver to ChromeDriver v2.36 level.
• Keep Chrome version at Chrome v65.x levels. (as per ChromeDriver v2.36 release notes)
• Clean your Project Workspace and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Chrome version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Chrome.
• Execute your @Test.

An older version of the ChromeDriver is being spun off when the test is being run; to remedy:

• Ensure that you've gotten your browser up to date (v65-67) and get the latest version of the ChromeDriver executable(v2.38)
• Extract the ChromeDriver and explicitly set the System property when initializing the ChromeDriver object...

Ex:

1. System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver.exe");
2. WebDriver driver = new ChromeDriver();

I had encountered the same issue. The issue got resolved by updating the chromedriverexe. please check the compatibility of your chrome browser with chrome driver here To download chromedriver
