I have a custom page that copies items from one list in one site to another, and its failing with the exception above.

I tried checking the field using sharepoint manager but I didnt find anything strange. The field where its failing its a managed metadata column the strange thing its that the exception is shown when checking if the field[internalname] is != null

  foreach (SPListItem item in listItems)
                                {
                                    SPListItem targetItem = destinationList.Items.Add();
                                    foreach (SPField field in item.Fields)
                                    {
                                        if (!field.ReadOnlyField && field.InternalName !="Attachments")
                                        {
                                            if (item[field.InternalName] != null)
                                            {

Update 1:

I tried these 2 ways and I still have the same error, its a managedmetadata field so no idea why its happeningn

   //if (item.GetFormattedValue(field.InternalName) != null)               
                                        if (item[field.Id] != null)

I tried checking the field using sharepoint manager but I didnt find anything strange. Tthe field where its failing its a managed metadata column

  the strange thing its that the exception is shown when checking if the field[internalname] is != null
