anyone know why i would have an issue creating this search?

var paymentInstrumentSearch = search.create({
      type: "paymentcardtoken",
      filters: [["entity", "is", customer.internalId]],
      columns: [
        search.createColumn({
          name: "entity",
          sort: search.Sort.ASC,
          label: "Customer"
        })
      ]
    });
