Exception in 2/files/download: "unsupported_file"

[sanjeev_hansanur]

We are trying read content of paper file, getting below exception

com.dropbox.core.v2.files.DownloadErrorException: Exception in 2/files/download: "unsupported_file"
at com.dropbox.core.v2.files.DbxUserFilesRequests.download(DbxUserFilesRequests.java:1278)
at com.dropbox.core.v2.files.DbxUserFilesRequests.download(DbxUserFilesRequests.java:1297)
at com.amazonaws.kendra.connector.dropbox.model.item.PocInputStreamToString.main(PocInputStreamToString.java:36)

Below is code we are using 

DbxDownloader dbxDownloader= client.files().download("/First Paper.paper");
  // Metadata metadata=client.files().getMetadata("/document.docx");
    InputStream inputStream= dbxDownloader.getInputStream();
   DataInputStream dataInputStream = new DataInputStream(inputStream);
   String tmp;
   StringBuilder inputLine=new StringBuilder();
    while ((tmp = dataInputStream.readLine()) != null) {
        inputLine.append(tmp);
        //System.out.println(tmp);
    }

   System.out.println("File content--->"+inputLine.toString());

Similarly we are facing issue for docx,paperT and shortCut

The "unsupported_file" error means:

This file type cannot be downloaded directly; use DbxUserFilesRequests.export(String) instead.

You can find more information in the documentation linked there.

Hi @mansi2821,

What you mean "the same issue"? 🤔 Have you meet some file you can neither export nor download? What is this file type, if any, and what you are seeing on the corresponding metadata (is the file marked as downloadable there)? 🧐

You didn't post particular file metadata, but file type, you're referring to, is not usually downloadable, so:

Direct download - No.

Export - Yes. 😉

@mansi2821 I see you've also posted this in a new thread, so I'll follow up with you there.

For future reference, please note it is not necessary to post the same question in multiple threads.
