Getting the Following Error : System.NullPointerException: Attempt to de-reference a null object Trigger.CreateActivityOnLeadConverted: line 34, column 1
I am getting the following error :
Error: System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, CreateActivityOnLeadConverted: execution of AfterInsert caused by: System.NullPointerException: Attempt to de-reference a null object Trigger.CreateActivityOnLeadConverted: line 34, column 1: [] Class.leadconvert.BulkLeadConvert.handleOpportunityInserts: line 740, column 1 Class.leadconvert.BulkLeadConvert.convertLead: line 104, column 1
Below is the trigger I think is the problem but not sure Please help.

Below is the trigger I think is the problem but not sure Please help.
trigger CreateActivityOnLeadConverted on Opportunity (after insert) {
List<Task> tasksToInsert = new List<Task>();
List<User> usersToUpdate = new List<User>();
List<Lead_Quota_Audit__c> lstNewAudits = new List<Lead_Quota_Audit__c>();
Id wholsaleID = null;
List <RecordType> wId = [Select Id From RecordType where sobjecttype = 'Opportunity' and name = 'Wholesale' limit 1];
if ((wId != null) && (wId.size() == 1)) wholsaleID = wId[0].Id;
Set<Id> userIds = new Set<Id>();
for(Opportunity opp : Trigger.new){
userIds.add(opp.OwnerId);
}
Map<Id, User> usersById = new Map<Id, User>([SELECT Id, Name, Leads_Assigned_Current_Month__c, Leads_Assigned_Current_Week__c FROM User WHERE Id IN :userIds]);
for(Opportunity opp : Trigger.new){
if (opp.RecordTypeId != wholsaleID) {
if (opp.ConvertedLeadID__c != null) {
Task task = new Task(
Type = 'Call',
Subject = 'Lead Status Changed to Converted',
ActivityDate = Date.Today(),
WhatId = opp.Id,
OwnerId = UserInfo.getUserId(),
Status = 'Completed',
Call_Screener_Transfered__c = opp.CS_Transferred__c
);
tasksToInsert.add(task);
if(opp.Lead_Status__c == 'Open'){
User u = usersById.get(opp.OwnerId);
if(u != null){
u.Leads_Assigned_Current_Month__c++;
u.Leads_Assigned_Current_Week__c++;
usersToUpdate.add(u);
Lead_Quota_Audit__c audit = new Lead_Quota_Audit__c(
Lead__c = opp.ConvertedLeadID__c,
User__c = u.Id,
Old_Owner__c = u.Name
);
lstNewAudits.add(audit);
}
}
}
}
}
insert tasksToInsert;
update usersToUpdate;
if(lstNewAudits.size() > 0) {
insert lstNewAudits;
}
}
The user record should be having null value for the field "Leads_Assigned_Current_Month__c". In Line number 34, when we try to increment the null value, "Attempt to de-reference a null object " error is received. To fix this, initialize the variable if it is null
if(u.Leads_Assigned_Current_Month__c == null) { // If it is a text variable, use string.isBlank(u.Leads_Assigned_Current_Month__c)
u.Leads_Assigned_Current_Month__c == 1;
}
else {
u.Leads_Assigned_Current_Month__c++;
}
