I’m getting this error. After this error the code stops working and then works again.

List<Map<String, Object>> rpkListesi = yedekRepository.getYedekParcaRaporuRpkListesi(rpkParams1);
                    if (rpkListesi != null && !rpkListesi.isEmpty()) {
                        document.newPage();
                        PdfPTable pdfPTable = new PdfPTable(1);
                        pdfPTable.addCell(new Phrase());
                        pdfPTable.setSpacingAfter(50);
                        document.add(pdfPTable);
                        resimDiyagramEkle(document, writer, "dokuman", rpkListesi.get(0).get("dosyaPath").toString(), "S", true);
                        PdfPTable rpkTable = yedekRpkTableOlustur(document, font11Bold, font10, !isNullOrEmpty(rpkListesi));

                        Map<String, Object> rpkParams2 = new HashMap<>();
                        rpkParams1.put("dokumanId", rpkListesi.get(0).get("dokumanId"));
                        rpkParams1.put("parcaId", yedekLahika.get(j).get("parcaId"));

                        List<Map<String, Object>> malzemeAciklamasi = yedekRepository.getYedekRpkListesi(rpkParams1);
                        rpkTable = rpkEkle(rpkTable, malzemeAciklamasi.get(0), font10, font9, font6);
                        document.add(rpkTable);
                    }

The error occurs from the following lines of code

List<Map<String, Object>> rpkListesi = yedekRepository.getYedekParcaRaporuRpkListesi(rpkParams1);

List<Map<String, Object>> malzemeAciklamasi = yedekRepository.getYedekRpkListesi(rpkParams1);

Here is the code in repository

 public List<Map<String, Object>> getYedekParcaRaporuRpkListesi(Map<String, Object> params) {
        String queryStr = "" +
                "SELECTn" +
                " d.id as dokuman_id,n" +
                " d.dosya_adi,n" +
                " d.dosya_pathn" +
                " FROM DOKUMAN D,PARCA_LKN PL,LKN L n" +
                " WHERE PL.PARCA_ID = :parcaIdn" +
                "       AND PL.DOKUMAN_ID = D.IDn" +
                "       AND PL.LKN_ID = L.IDn" +
                "       AND L.PROJE_KODU = :projeKodun" +
                "       AND L.BORDA_NO = :bordaNon" +
                "       AND l.yol like ('%.' || :lknId || '.%')n" +
                "       AND pl.miktar > 0";

        Query query = entityManager.createNativeQuery(queryStr);

        if (isNotEmpty(params.get("parcaId")))
            query.setParameter("parcaId", params.get("parcaId"));

        if (isNotEmpty(params.get("projeKodu")))
            query.setParameter("projeKodu", params.get("projeKodu"));

        if (isNotEmpty(params.get("bordaNo")))
            query.setParameter("bordaNo", params.get("bordaNo"));

        if (isNotEmpty(params.get("lknId")))
            query.setParameter("lknId", params.get("lknId"));

I use this code in another page but I don’t get an error there. What do I need to do to fix it?
