Hello Everyone,

I hope you can help me on this..Im working with singleEmail to send an email to a particular sales representative on every territory. but every time I invoked my trigger via update of my objects, it returns an exception. The error is: System.EmailException: SendEmail failed. First exception on row 0; first error: INVALID_ID_FIELD, WhatId is not available for sending emails to UserIds.\.: Trigger.Notify_Rep_Trigger: line 90, column 21

my code is written below:

Account territory = [select Territory_Name__c from Account where Id =:data.Account_ID__c];
           
            if(territory.Territory_Name__c != null)
            {
               
                List<string> splitID = territory.Territory_Name__c.split(';', -1);
                Set<string> tID = new Set<string>();
                tID.clear();
               
                List<Territory> territoryId = [Select id From Territory where name in :splitID];
               
                List<UserTerritory> usersId = [Select UserId From UserTerritory where territoryid in :territoryId];
               
                for(integer x=0; x < usersId.size(); x++)
                {
                        tID.add(usersId[x].UserId);
                }
               
                List<User> emailAdd = [select Id, email from User where Id in :tID];
               
                Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                List <String> Addresses = new List<String>();
           
                for(integer i=0; i < emailAdd.size(); i++)
                {
                    //String[] toAddresses = new String[] {emailAdd[i].email};
       
                    //mail.setToAddresses(toAddresses);
                    mail.setCcAddresses(ccAddresses);
                   
                    mail.setBccSender(true);
                    mail.setUseSignature(false);
                    mail.setSaveAsActivity(false);
                   
                    String toTargetObjects = (string)emailAdd[i].Id;
                   
                    system.debug('target object deb:'+toTargetObjects);
                    system.debug('data id deb:'+data.Id);
                   
                    mail.setTargetObjectId(toTargetObjects);
                    mail.setWhatId(toTargetObjects);
       
                    mail.setTemplateId(templateId);
                   
                    Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
                }
            }
        }

any suggestion? I would really appreciate it if you can help me on this.


Thanks in advance,

Wilson
