updatedVoucher_processings viewPaymentDetails mutation

[MagnusHolen]

We are having trouble getting the viewPaymentDetails mutation to work.

GraphQL:

mutation UpdatedVoucherViewPaymentDetails {
  useCompany(no: xxx) {
    updatedVoucher_processings {
      viewPaymentDetails(
        filter: {
          _and: [
             {voucherJournalNo: {_eq: 62617}},
             {batchNo: {_eq: 7}},
             {lineNo: {_eq: 2}} ]
         }
      ) {
        succeeded
        items {
           paymentDetails
        }
      }
    }
  }
} 

We can fetch the payment details on this transaction in the NXT GUI,

but the query returns success = true and "paymentDetails": null.

Any pointers on what is wrong? Have anyone gotten this mutation to work?
