Hi @peifengyuan!

I think there are two potential ways to solve your problem:

1. 
   
   

   If you would like to continue to use an Apex trigger, you will need to use the createFolderForRecordId method call in a separate class. The Box Developer Toolkit leverages future callouts which is why you’re receiving this error.

   
   
   



2. 
   
   

   Alternatively, you can leverage the Salesforce Flow invocable actions that we ship with the Box for Salesforce managed package: https://developer.box.com/guides/tooling/salesforce-toolkit/flow-actions/

   
   
   

Hi @kadams


Thank you so much！！


I will try it out right away. Have a great day!

Thank you & Best Regards,

Hi @kadams


Sorry to disturb you again.


I tried separating the class and calling it from the trigger, but I still encountered the same error. Here is my code. Could you please tell me what is wrong with it?

BoxCommonUtil class

public class BoxCommonUtil {


    public BoxCommonUtil() {


    }





    public static void creatBoxFolderNew(Project__c [] newObjs) {





        System.debug('run create box folder');


        // IdList


        List<Id> projectIdList = new List<Id>();


        for(Project__c project : newObjs) {


            projectIdList.add(project.Id);


        }





        List<Project__c> boxProjectList = [SELECT Id,


                                                  Name,


                                                  PJ_ProjectKeyNo__c,                   


                                                  PJ_ProjectManagementDepartment__c,


                                                  FROM Project__c 


                                                  WHERE Id IN :projectIdList];





        // get Folder Details info


        Map<String, box__Folder_Details__c> bfdMap = box__Folder_Details__c.getAll();


        //Map<Folder Name, ForderId>


        Map<String, String> bfdNameIdMap = new Map<String, String>();


        for(box__Folder_Details__c bfd : bfdMap.values()) {


            bfdNameIdMap.put(bfd.box__Folder_Name__c, bfd.box__FolderId__c);


        }





        List<Project__c> updateProjectList = new List<Project__c>();





        box.Toolkit boxToolkit = new box.Toolkit();





        for(Project__c project : boxProjectList) {





            String folderNameOverride = project.PJ_ProjectKeyNo__c + '_' + project.Name;


            System.debug(folderNameOverride);


            System.debug(project.Id);


            String projectFolderId;


            try{


                // create box Folder


                projectFolderId = boxToolkit.createFolderForRecordId(project.Id, folderNameOverride, true);


                // get recent error


                System.debug(boxToolkit.mostRecentError);


            } catch(Exception e) {


                System.debug(e.getMessage());


            }





            // move folder


            String newParentFolderId = bfdNameIdMap.get(project.PJ_ProjectManagementDepartment__c);


            // run move folder


            Boolean isMoved = boxToolkit.moveFolder(projectFolderId, newParentFolderId, null);


            System.debug(isMoved);





            // 


            project.PJ_ProjectFolderId__c = projectFolderId;


            project.PJ_BoxLink__c = System.Label.CON_BOX_Url + projectFolderId;


            updateProjectList.add(project);


        }


        boxToolkit.commitChanges();





        update updateProjectList;





    }


}

Trigger Handler class

    public void onAfterInsert(Project__c [] newObjs, Map<ID, Project__c> newObjMap) {





        // Create Box Folder


        try {


            // creatBoxFolder(newObjs);


            BoxCommonUtil.creatBoxFolderNew(newObjs);


        } catch(Exception e) {


        }


        


    }

Hi @kadams

The issue has been resolved! I forgot to include the @future annotation…


I made the following modifications to the source code.


thank you so much!!

BoxCommonUtil class

public class BoxCommonUtil {


public BoxCommonUtil() {


}


@future (callout=true)


// public static void creatBoxFolderNew(Project__c c] newObjs) {


public static void creatBoxFolderNew(List<ID> projectIdList) {
