Groovy: Script execution has failed [reason: java.lang.IllegalArgumentException: Value is instanceof Collection but cannot be empty collection for key: catalogVersions

[former_member1049674]

Hi,

I am getting the following error when I run the following groovy script. Can anyone advice why I am getting the error message?

Thank you

Script execution has failed [reason: java.lang.IllegalArgumentException: Value is instanceof Collection but cannot be empty collection for key: catalogVersions]

The script is:

 import de.hybris.platform.cms2.model.contents.components.AbstractCMSComponentModel;
 import de.hybris.platform.cms2.model.navigation.CMSNavigationNodeModel;
 import de.hybris.platform.acceleratorcms.model.components.NavigationBarComponentModel;
 import de.hybris.platform.cms2.servicelayer.services.CMSComponentService;
 import java.util.ArrayList;
 import java.util.List;
 
 CMSComponentService cmsComponentService = spring.getBean("cmsComponentService");
 
 AbstractCMSComponentModel component = (AbstractCMSComponentModel) cmsComponentService.getSimpleCMSComponent("categoryId");
 
 if (component != null){
 
         CMSNavigationNodeModel levels=((NavigationBarComponentModel)component).getNavigationNode();
         if (levels!=null){
             List<CMSNavigationNodeModel> listLevels=levels.getChildren();
             for (CMSNavigationNodeModel level:listLevels){
                 println " level: " + level.getUid();
                 for (CMSNavigationNodeModel subLevel1:level.getChildren()){
                     println " subLevel1: " + subLevel1.getUid();
                 }
             }
         }
         
 }

You need to set the session catalog version.

e.g.

catalogVersionService.setSessionCatalogVersion 'Default', 'Staged'

Also, although that will run as Groovy, it's not very groovy. What are all those types and semi colons doing there? And you definitely don't need to access the application context directly to retrieve beans.

Perhaps something more like this?

catalogVersionService.setSessionCatalogVersion 'myContentCatalog','Staged'
component = cmsComponentService.getSimpleCMSComponent('MyAccountComponent')
component?.navigationNode?.children.each { level ->
    println " level: ${level.uid}"
    level.children.each { subLevel ->
        println " subLevel1: ${subLevel1.uid}"
    }
}
