How to map return line item with Fulfillment items?

GraphQL Admin API Troubleshooting

Hi @Maulik_Shah_RAB - the fulfillmentLineItem field does exist on ReturnLineItem - the trick is that returnLineItems returns the ReturnLineItemType interface rather than the type, so you need an inline fragment to access it:

query getReturn($id: ID!) {
  return(id: $id) {
    returnLineItems(first: 10) {
      nodes {
        ... on ReturnLineItem {
          id
          quantity
          fulfillmentLineItem {
            id
            lineItem {
              id
              name
              sku
            }
          }
        }
      }
    }
  }
}

This came up a few times before - same solution worked in this thread and this one.
