Katalon Jenkins integration

Hi, i have 2 Servers and want to execute Katalon Tests via Remote. As workspace i’m using github. In jenkins i have following job: on the Server 1(Linux) i run Selenium Hub and after that run the Katalon Test command. Unfortunately i have error: java.lang.NoClassDefFoundError: Unable to load class com.kms.katalon.keyword.applitools.BasicKeywords due to missing dependency org/openqa/selenium/WebElement. Does anyone has an idea how i can solve this problem?
Katalon Version is 7.6.2.205.
