Hi Krishna,

For the below If condition just add another condition as below.
  
if(objOrder.implanting_physician__c != null && mapOrderType_Role.containskey(objOrder.Type) && mapOfUserId.containskey(objOrder.implanting_physician__c) ){

Let me know if you still face the issue and also the line of error you are getting

If this solution helps, Please mark it as best answer.

Thanks,

Hi Krishna,

Please use below code:-
  
public static void populatePhysicianOnCareTeam(List<Order> newList){
        List<CareTeam__c> mapCaseTeam = new List<CareTeam__c>();
        Set<Id> setOfPhysicianId = new Set<Id>();
        Map<Id, User> mapOfUserId = new Map<Id, User>();
        for(Order objOrder : newList){
            setOfPhysicianId.add(objOrder.implanting_physician__c ); 
        }
        Map<String, String> mapOrderType_Role= new Map<String, String>{'NROP'=>'Trialing Physician', 'NROP'=>'Implanting Physician',
            'NREP'=>'Replacement Physician', 'NREV'=>'Revision Physician'};
                if(!setOfPhysicianId.isEmpty()){
                    for(User user : [SELECT Id, Name, ContactId FROM User WHERE ContactId =: setOfPhysicianId]){
                        mapOfUserId.put(user.ContactId, user);

        for(Order objOrder : newList){
            if(objOrder.implanting_physician__c != null && mapOrderType_Role.containskey(objOrder.Type) && mapOfUserId.size() > 0){
