Find a element (object) in a Web Table

Hi !

I’m trying to find out if an element is present or not in a web table and if it is not I click on the line of the table. I followed the topic :

Here is the table and the element that I want to know if it’s present or not :

and here is the script that I made :

So you doubt if I created the topic it’s because that doesn’t work… I tried to fix that but i have allway a different error. The actuel error is :
groovy.lang.MissingMethodException: No signature of method:$EventFiringWebElement.getAttribute() is applicable for argument types: (com.kms.katalon.core.testobject.TestObject, java.lang.Boolean) values: [TestObject - ‘Object Repository/Page_Kibati Mes interventions/i_DYC_fa fa-check’, …]
Possible solutions: getAttribute(java.lang.String)

Like the error says, don’t put a TestObject in your call to getAttribute().
