Question

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

Answer 1

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.
