[SharePoint List Source [296]] Error: Microsoft.SqlServer.Dts.Pipeline.DoesNotFitBufferException: The value is too large to fit in the column data area of the buffer.

I have a running package which reads data from SharePoint List and dumps into SQL tables. I have 3 new list columns which I want to update into SQL table.

1) I opened container for this list and table

2) Refreshed mapping tab in SharePoint list source item properties

3) mapped columns in OLE DB Destination

When I ran this container, i got following error.

[SharePoint List Source [296]] Error: Microsoft.SqlServer.Dts.Pipeline.DoesNotFitBufferException: The value is too large to fit in the column data area of the buffer.at Microsoft.SqlServer.Dts.Pipeline.PipelineBuffer.SetString(Int32 columnIndex, String value)at Microsoft.Samples.SqlServer.SSIS.SharePointListAdapters.SharePointListSource.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers)at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostPrimeOutput(IDTSManagedComponentWrapper100 wrapper, Int32 outputs, Int32[] outputIDs, IDTSBuffer100[] buffers, IntPtr ppBufferWirePacket)

Soruce Sharepoint list columns are string (255 chars) and date time. Thus I tried setting external column size as 260 chars and output columns as 300 chars, to avoid any truncation or issues. But still same issue.

Question: How can I verify which column or data is causing issue?
