NullReferenceException when calling CustomerContext from Scheduled job

Hi,

I have an sceduledTask configured in EPiServer CMS 6.1.379.0 to export Customers from EPiServer Commerce 1 R2 SP2.
It doesn't matter which method i call on the CustomerContext, they all throw an NullReferenceException when i run this task from the EPiServer CMS backend by pressing the button to start the task manually.

StackTrace:
at Mediachase.BusinessFoundation.Data.Business.BusinessManager.Execute(Request request)
at Mediachase.BusinessFoundation.Data.Business.BusinessManager.List(String metaClassName, FilterElement[] filters)
at Mediachase.Commerce.Customers.CustomerContext.<InnerGetAllContacts>d__40.MoveNext()
at System.Linq.Buffer`1..ctor(IEnumerable`1 source)
at System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source)
at Mediachase.Commerce.Customers.CustomerContext.<GetAllContacts>b__3f()
at Mediachase.Commerce.Customers.CustomerContext.GetCachedValue(String key, TimeSpan timeout, Func`1 cachedValueGetter)
at Mediachase.Commerce.Customers.CustomerContext.GetAllContacts()
at EPiServer.Business.Commerce.Sample.SceduledTasks.ExportCustomers.Execute() in D:\xxxxx:line xx

My code snippet:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Xml;
using EPiServer.BaseLibrary.Scheduling;
using EPiServer.PlugIn;
using Mediachase.BusinessFoundation.Data;
using Mediachase.BusinessFoundation.Data.Business;
using Mediachase.Commerce.Customers;
using log4net;
using log4net.Repository.Hierarchy;

namespace EPiServer.Business.Commerce.Sample.SceduledTasks
{
	[ScheduledPlugIn(DisplayName = "Export customers")]
	public class ExportCustomers : JobBase
	{
		public ExportCustomers() : base()
		{
			IsStoppable = false;
		}

		public override string Execute()
		{
			IEnumerable<CustomerContact> searchResult = CustomerContext.Current.GetAllContacts();
		}
	}
}

I hope someone has a solution how to work around this NullReferenceException, but any help would be greatly appreciated!

You need to initialize SqlContext like below before calling your code because in Episerver Schedule job, it's null.

SqlContext.Current = new SqlContext(ConfigurationManager.ConnectionStrings["EcfSqlConnection"].ConnectionString);

Thanks Hiep Dinh To!

Not only the SqlContext.Current was null but also the DataContext.Current.

When i also added the following line i got my results as expected.

DataContext.Current = new DataContext(ConfigurationManager.ConnectionStrings["EcfSqlConnection"].ConnectionString);

Thanks again!
