I have an apex extension controller that I'm trying to send to my porduction org but i am getting the following error while validating from the inbound changeset. 
 

System.ListException: List index out of bounds: 1
Stack Trace: Class.AccountMapCtrl.buildAdditionalWhere: line 190, column 1 Class.AccountMapCtrl.getAccounts: line 84, column 1 Class.AccountMapCtrlTest.testAll: line 26, column 1

Here is the test class and my apex extension controller
 

@isTest(SeeAllData=true)

public class AccountMapCtrlTest{
    static testmethod void testAll(){
        Account acc = new Account(
            Name = 'testAcc',
            Description = 'test description',
            Industry = 'information tech',
            Type = 'Press',
            ShippingLatitude = 22.6211,
            ShippingLongitude = 88.4649,
            RecordTypeId = Account.SObjectType.getDescribe().getRecordTypeInfosByName().get('Site').getRecordTypeId()
        );
        insert acc;

        AccountMapCtrl.describePickList('AccountSource');
        AccountMapCtrl.getFields('Account', 'AccountMap_Filters');
        List<AccountMapCtrl.Field> fields = new List<AccountMapCtrl.Field>();
        Schema.FieldSet fieldset = Schema.SObjectType.Account.fieldSets.getMap().get('AccountMap_Filters');
        for(Schema.FieldSetMember member : fieldset.getFields()){
            fields.add(new AccountMapCtrl.Field(member));
        }
        AccountMapCtrl.getAccounts(Json.serialize(fields), null);
        AccountMapCtrl.getVendors(Json.serialize(fields), null);
        AccountMapCtrl.getManagers();
        AccountMapCtrl.getFieldCSV('Account');
    }

}

Controller:

Public Class AccountExtensionController{
   private Account acc;
   public List<Bids_Sent__c> bidsList {get;set;}
   public Map<String,List<Site_Bid_Details__c>>  bidsMap {get;set;}
   public AccountExtensionController(ApexPages.StandardController sc){
       acc = (Account)sc.getRecord();
       bidsList = new List<Bids_Sent__c>();
       bidsList = [SELECT Id,IsAddedToPDF__c,Customer__r.Service_Agreement_Verbiage__c,Site__c,Site__r.Contract_Start_Date__c,Site__r.Contract_End_Date__c,Site__r.Customer_Location_ID__c,Service_Year__c,Customer__r.Contract_Start_Date__c,Name,Customer__r.Contract_End_Date__c,Site__r.Name,Customer__r.Name,Primary_Contact__r.FirstName,Site__r.BillingCity,Site__r.BillingState,Site__r.BillingStreet,Site__r.BillingPostalCode  FROM Bids_Sent__c WHERE Awarded__c =: acc.Id AND IsAddedToPDF__c=true];
    
    Set<Id> bidId = new  Set<Id>();  
    for(Bids_Sent__c bs : bidsList){
       bidId.add(bs.Id);
    }
     
    bidsMap = new Map<String,List<Site_Bid_Details__c>> ();
    for(Site_Bid_Details__c bd : [SELECT Id, Bid_Name__r.Name,Site__c,Contract_Start_Month__c,Site__r.Customer_Location_ID__c,Cost__c,Customer__r.Contract_Month__c,Increment__c,Total__c,Price__c,Scope__c,Bid_Name__r.Service_Type__c,Number_of_Months__c,Retainer_Fee__c,Monthly_Payment__c,UOM__c  FROM Site_Bid_Details__c WHERE Bid_Name__c IN : bidId]){
        
        if(bidsMap.containsKey(bd.Bid_Name__r.Name)){
  System.debug('CONTAINS KEY: ' + bd.Bid_Name__r.Name);
  bidsMap.get(bd.Bid_Name__r.Name).add(bd);
} else { 
  System.debug('CREATE: ' + bd.Bid_Name__r.Name);
  bidsMap.put(bd.Bid_Name__r.Name,new List<Site_Bid_Details__c>{bd}); 
}
    } 

}
