Below is my code:

   val document: PdfDocument = PdfDocument()
        val pageInfo: PdfDocument.PageInfo? = bitmap?.width?.let { it1 ->
            bitmap?.height?.let { it2 ->
                PdfDocument.PageInfo.Builder(
                    it1,
                    it2, 1).create()
            }
        }
        val page: PdfDocument.Page  = document.startPage(pageInfo)

        val canvas: Canvas = page.canvas
        bitmap?.let { it1 -> canvas.drawBitmap(it1, 0f, 0f, null) }
        document.finishPage(page)

        val mediaStorageDir = File(Environment.getExternalStorageDirectory(), "Papers")

        if (mediaStorageDir.exists()) {
            document.writeTo( FileOutputStream(mediaStorageDir))
            document.close()
        }

What I am doing wrong?

I a trying to create folder in internal storage in android

FWIW, your code is set up for external storage.

Someone please let me know what I am doing wrong any help would be appreciated.

Papers/ appears to exist and is a directory. writeTo() takes a file, not a directory. Try something like:

        val mediaStorageDir = File(Environment.getExternalStorageDirectory(), "Papers")

        if (mediaStorageDir.exists()) {
            val pdfFile = File(mediaStorageDir, "something.pdf")

            document.writeTo( FileOutputStream(pdfFile))
            document.close()
        }
