android - Unable to send pdf file via intent to any application except Whatsapp

Question

I'm trying to share a pdf file(which was created using pdfbox library) using intent to other apps, but when I send it to Gmail or telegraph, I get error called unsupported attachment. However, I am able to successfully send it via Whatsapp. Here's my code for sharing:

 fun shareIntent(context: Context, position: Int) {
         val sharingIntent = Intent(Intent.ACTION_SEND)
         sharingIntent.type = "application/pdf"
         val file= docAdapter.getItem(position).path
         val uri = Uri.parse(file)
         sharingIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY)
         sharingIntent.putExtra(Intent.EXTRA_STREAM, uri  )
         context.startActivity(Intent.createChooser(sharingIntent, "Share via"))
     }
