get the content provider uri crash in android

I have the following file path on my device

file:///storage/emulated/0/DCIM/IMG_20190206_141330.jpg

I am trying to get content provider for it to be able to rotate it using this method in kotlin

private fun Uri.getPath(ctx: Context): String? {
    val projection = arrayOf(MediaStore.Images.Media.DATA)
    val cursor = ctx.contentResolver.query(this, projection, null, null, null) ?: return null
    val columnIndex = cursor.getColumnIndexOrThrow(projection[0])
    cursor.moveToFirst()
    val s = cursor.getString(columnIndex)
    cursor.close()
    return s
}

I am getting the following crash

 java.lang.NullPointerException: println needs a message

I am trying to get content provider for it

That's not going to work. A content Uri has content:// as the scheme. Yours has file:// as the scheme.

for it to be able to rotate it

You can get rid of Uri.getPath() (which will not work for most Uri values, even those with content:// schemes). Use openInputStream() on a ContentResovler to open an InputStream on the content identified by the Uri (works for both content:// and file:// Uri values). Then, use that InputStream to read in the image to rotate it.
