ExceptionConverter: java.io.IOException: Stream Closed when trying to create a PDF using iText

Question

I'm working on PDF related project and I want to create a PDF from the existing PDF.

all things are done but when I created a final PDF at that time this exception was thrown at the line of document.close(); at the method of savePDF which describe below.

• Create new PDF from existing PDF adding PdfImportedPage.

here is my code

The app crashes only when we add a new page

private void createAndAddPage(Bitmap bitmap) {

    try {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
        byte[] byteArray = stream.toByteArray();
        Document document = new Document();
        File file = getPdfFile();
        FileOutputStream fileOutputStream = new FileOutputStream(file);
        PdfWriter pdfWriter = PdfWriter.getInstance(document, fileOutputStream); //  Change pdf's name.
        document.open();
        Image image = Image.getInstance(byteArray); // Change image's name and extension.
        float scaler = ((document.getPageSize().getWidth() - document.leftMargin()
                - document.rightMargin() - 0) / image.getWidth()) * 100; // 0 means you have no indentation. If you have any, change it.
        image.scalePercent(scaler);
        image.setAlignment(Image.ALIGN_CENTER);
        document.add(image);
        document.close();

        PdfReader pdfReader = new PdfReader(file.getPath());
        PdfImportedPage pdfImportedPage = pdfWriter.getImportedPage(pdfReader, 1);
        pageAdjustmentAdapter.AddPage(new PageAjdustAdapter.PdfPage(pdfImportedPage, bitmap));

    } catch (Exception e) {
        e.printStackTrace();
    }
}

method when saves a final PDF(crash happens in this method)

    private void savePDF(PageAjdustAdapter pageAdjustment) {
       
                mPDFpages = pageAdjustment.getUpdatedList();
             
                try {

                    pdfWriter.setPageEvent(new RotateEvent());
                    document.open();

                    PdfContentByte pdfContentByte = pdfWriter.getDirectContent();

                    for (int i = 0; i < mPDFpages.size(); i++) {
                        pdfContentByte.addTemplate(mPDFpages.get(i).page, 0, 0);
                        document.newPage();
                    }

                } catch (Exception e) {
                    Log.d(TAG, "run: -> " + e.getMessage());
                    e.printStackTrace();
                } finally {
                    if (document.isOpen()) document.close();
                    actionListener.onEnd("Success");
                
                }

    }
