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();
                 }
             }
         }
         
 }

Hi ,

In Above Your Code Snippet CatalogVersion not give the argument for getting the cmscomponent.Use Bellow Code

 import de.hybris.platform.acceleratorcms.model.components.NavigationBarComponentModel
 import de.hybris.platform.catalog.CatalogVersionService
 import de.hybris.platform.catalog.model.CatalogVersionModel
 import de.hybris.platform.cms2.model.contents.components.AbstractCMSComponentModel
 import de.hybris.platform.cms2.model.navigation.CMSNavigationNodeModel
 import de.hybris.platform.cms2.servicelayer.services.CMSComponentService
 import de.hybris.platform.core.Registry
 
 CMSComponentService cmsComponentService = spring.getBean("cmsComponentService");
 CatalogVersionModel version=Registry.getApplicationContext().
         getBean("catalogVersionService",CatalogVersionService.class).getCatalogVersion("apparelProductCatalog", "Online");
 List versionslist=new ArrayList();
 versionslist.add(version);
 AbstractCMSComponentModel component = (AbstractCMSComponentModel) cmsComponentService.getAbstractCMSComponent("A101010",versionslist);
 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();
             }
         }
     }
 }
