    Assuming you are using TelegramBot SDK from rubenlagus (https://github.com/rubenlagus/TelegramBots), as I faced same issue. Below is my solution.

    GetFile getFile = new GetFile().setFileId(fileId);
String filePath = execute(getFile).getFilePath();
File file = downloadFile(filePath, outputFile);

    I had the same problem.
    This was my solution. Not very nice but it works.

    if (update.getMessage().hasDocument()){
        String doc_id = update.getMessage().getDocument().getFileId();
        String doc_name = update.getMessage().getDocument().getFileName();
        String doc_mine = update.getMessage().getDocument().getMimeType();
        int doc_size = update.getMessage().getDocument().getFileSize();
        String getID = String.valueOf(update.getMessage().getFrom().getId());

        Document document = new Document();
        document.setMimeType(doc_mine);
        document.setFileName(doc_name);
        document.setFileSize(doc_size);
        document.setFileId(doc_id);

        GetFile getFile = new GetFile();
        getFile.setFileId(document.getFileId());
        try {
            org.telegram.telegrambots.meta.api.objects.File file = execute(getFile);
           downloadFile(file, new File("./data/userDoc/"+getID+"_"+doc_name));
        } catch (TelegramApiException e) {
            e.printStackTrace();
        }


    }

    Here I got this solution
