Error:java.lang.NullPointerException run time Exception in apex Class

Hi,

 

I am importing the data in Contact using Apex Class.

 

Code to set the data in Contact Object is:

Contact createObject(String[] records){
        String gender=records[headerMap.get('gender')];
         Contact upsertContact=new Contact();
        try{
            if(gender!=null && !gender.trim().equals('')){
                //System.debug('gender1====='+gender);
                if((genderMap==null)|| (genderMap!=null && !genderMap.containsKey(gender.toLowerCase()))){
                	if(genderMap==null){
                		genderMap=new Map<String,String>();
                	}
                    Supplier_Value__c svc=new Supplier_Value__c(Name=gender);
                    if(cfc!=null){
                        svc.Conversion_Field__c=cfc[0].Id;
                    }
                    insert svc;
                    genderMap.put(gender.toLowerCase(),null);
                    businessServices.getGeneralServices().sendMailToAdministrator('New Gender Value '+gender+' added in the database by Organization '+records[headerMap.get('clientid')]);            
                }
                upsertContact.Salutation =genderMap.get(gender.toLowerCase());
            }
            //upsertContact.OwnerId=ftpDetailsDto.getOwnerId();
       
            upsertContact.FirstName =records[headerMap.get('firstname')];
            upsertContact.LastName =records[headerMap.get('lastname')];
            upsertContact.MailingStreet =records[headerMap.get('mailingstreet')];
            upsertContact.MailingPostalCode=records[headerMap.get('mailingpostalcode')];
            upsertContact.MailingCity=records[headerMap.get('mailingcity')];
            upsertContact.MailingCountry=records[headerMap.get('mailingcountry')];
            upsertContact.HomePhone =records[headerMap.get('phone')];
            if(records[headerMap.get('email')]!=null && records[headerMap.get('email')]!=''){             
                matcher myMatcher = myPattern.matcher(records[headerMap.get('email')]);
                if(myMatcher.matches()){
                    upsertContact.npe01__HomeEmail__c=records[headerMap.get('email')];    
                }
            }
       
        upsertContact.npe01__PreferredPhone__c='Household';
        upsertContact.npe01__Preferred_Email__c='Home';
        upsertContact.Title=records[headerMap.get('academictitle')];
        upsertContact.BANKACCOUNT__c=records[headerMap.get('bankaccount')];
        Date dob=businessServices.getGeneralServices().convertStringToDate(records[headerMap.get('birthdate')]);
        if(!records[headerMap.get('birthdate')].equals('') && dob!=null && (dob<(Date.newInstance(1700,01,01)) || dob>(Date.newInstance(4000,12,30)))){
            
            numberOfInvalidRecords++;
            //errorList.add('numberOfInvalidRecords  '+ numberOfInvalidRecords);
            throw new DateRangeException('');
        }
        upsertContact.Birthdate=dob;
        upsertContact.EXTERNALID__c=records[headerMap.get('donorid')];
        
        if(records[headerMap.get('status')].equalsIgnoreCase('DoNotCall')){
            upsertContact.DoNotCall=true;
        }else if(records[headerMap.get('status')].equalsIgnoreCase('Deceased')){
            upsertContact.Deceased__c=true;
        }else if(records[headerMap.get('status')].equalsIgnoreCase('DoNotMail')){
            upsertContact.Do_Not_Mail__c=true;
        }
        if(lastModifiedDateForImport==null || (lastModifiedDateForImport.daysBetween(businessServices.getGeneralServices().convertStringToDate(records[headerMap.get('lastmodifydate')]))>0)){
            lastModifiedDateForImport=businessServices.getGeneralServices().convertStringToDate(records[headerMap.get('lastmodifydate')]);
        }
       // upsertContact.ClientId__c=records[headerMap.get('clientid')];
       upsertContact.ClientId__c=detailsDto.getOrganizationId();
       }catch(Exception er){           
           errorList.add('Error in create object===:  '+ er.getMessage()); 
        }
        return upsertContact;
    }
This contact object returned is set in a List for bulk upsert function.
 
The code for bulk upsertion is:
 
Database.UpsertResult[] lsr=Database.upsert(upsertContactList,Contact.EXTERNALID__c,false);
      // checks if data inserted successfully or not,if not then add error messages in errorlist
        Integer index=0;
        for(Database.UpsertResult sr:lsr)
        {
            if(!sr.isSuccess()){
                Database.Error err=sr.getErrors()[0];                    
		errorList.add('Error:  '+ err+'  upsertContactList '+upsertContactList[index]);
              }
                        index++;
        }
 
 
But i am getting error:
 
Error: Database.Error[getFields=null;getMessage=java.lang.NullPointerException;getStatusCode=System.StatusCode.UNKNOWN_EXCEPTION;] 
 
upsertContactList Contact:{ClientId__c=MSA, EXTERNALID__c=100038558, Salutation=Mr., LastName=Hillenaar, HomePhone=null, Title=null, npe01__Preferred_Email__c=Home, BANKACCOUNT__c=138449317, MailingCity=LEIDEN, MailingStreet=Vlietweg 3, MailingCountry=The Netherlands, npe01__PreferredPhone__c=Household, MailingPostalCode=2323 LA, FirstName=J.A., Birthdate=null}
 
 
I a not able to figure out the problem.
 
Please guide me.
 
Thanks in advance.
