Getting java.lang.UnsupportedOperationException: getDomAttribute for Select in Selenium 4

Question

I am getting java.lang.UnsupportedOperationException: getDomAttribute for Select in Selenium 4. Does anyone know how to resolve this issue? My selenium version is 4.6.0. Tried multiple things but nothing worked..

java.lang.UnsupportedOperationException: getDomAttribute at org.openqa.selenium.WebElement.getDomAttribute(WebElement.java:131) at org.openqa.selenium.support.ui.Select.<init>(Select.java:54)

Answer 1

This error message...

java.lang.UnsupportedOperationException: getDomAttribute
at org.openqa.selenium.WebElement.getDomAttribute(WebElement.java:131)
at org.openqa.selenium.support.ui.Select.<init>(Select.java:54)

...indicates a dependency conflict and it's almost always a dependency management issue.

getDomAttribute() is a new addition in selenium4.

Solution

Ensure that:

• Your project is updated with the latest Selenium release. (current release being v4.10.0)
• Your project is correctly using the same version of selenium libraries for everything and resolve the dependency conflicts following the article HOW TO DEBUG DEPENDENCY CONFLICTS IN MAVEN AND GRADLE
