Hi Guys,

@dhanasekaran-anbalagan is the error with any files, or just this particular file? Specifically, can you try downloading smaller files and LMK if that works. Basically trying to isolate if this is an issue with very large files.

[dhanasekaran-anbalagan]

@diwakergupta thanks for the reply. smaller files ( less than 1GB ) we don't have an issue. The only issue with bigger file more the 2GB+

can you please guide me any workaround is there.

NOTE: One more info. the same file we are able to download via Python API

please let me know if you need more info

[mikaelmantel]

I got the same thing but with a smaller file (1,1 Mo) :

`root@pmx1:/home/dropbox/backup# ./dbx get "Operations/Tools/WinX32/7z920.exe" "Operations/Tools/WinX32/7z920.exe"

Error: unexpected end of JSON input`

[diwakergupta]

@mikaelmantel this looks like a different error (unexpected EOF vs. end of JSON input). Do you mind sending me the version info (dbxcli version) and verbose output (dbxcli -v get ...)? Also make sure you are working with the latest release.

[diwakergupta]

@dhanasekaran-anbalagan when you say you're able to download via the Python API, are you using the built-in helper utilities or have you written your own code using the API?

[dhanasekaran-anbalagan]

Yes, we are using built-in helper utilities, have attached example program.

#!/usr/bin/env python

import dropbox
import os
import logging
import urllib3

# to disable warnings.
urllib3.disable_warnings(urllib3.exceptions.InsecurePlatformWarning)
urllib3.disable_warnings(urllib3.exceptions.SNIMissingWarning)

level = "INFO"
logging.basicConfig(level=level, format="%(levelname)-10s| %(asctime)-10s | %(funcName)-10s | %(message)s")

TOKEN = ''
DBX = dropbox.Dropbox(TOKEN)

def dbx_downloader(dbx_location, local_fs_location):
    try:
        logging.info("let's start download file from DropBox dbx_location=%s and local_fs_location=%s", dbx_location,
                     local_fs_location)
        DBX.files_download_to_file(
            download_path=local_fs_location,
            path=dbx_location
        )
        logging.info("Download completed successfully ..")
    except:
        import traceback
        traceback.print_exc()

if __name__ == '__main__':
    import argparse
    from argparse import RawTextHelpFormatter

    description = '%r\n\nDropBox Downloader..\n%r' \
                  % ('_' * 60, '_' * 60)
    parser = argparse.ArgumentParser(description=description.replace("'", ""), formatter_class=RawTextHelpFormatter)
    parser.add_argument('--path', help='Please provide valid path from DropBox', type=str, required=True)
    parser.add_argument('--download_path', help='Please provide valid local destination', type=str, default=None)
    args = parser.parse_args()

    path = args.path
    filename = os.path.basename(path)
    download_path = filename if args.download_path is None else os.path.join(args.download_path, filename)
    dbx_downloader(dbx_location=path, local_fs_location=download_path)

@diwakergupta Oouupss, I did not see that the message was different.

This issue is still present (using version a871c88e22f4575d2f2cb1b77af9a91975acd296) when downloading large files. I have a 200 GB file which can reproduce this issue reliably. I can download 20 GB files, so the problem arises somewhere between these two sizes.

[edoyango]

Are there any updates on this? This is happening to me now with a 164GiB file:

Downloading 50 GiB/164 GiB
Error: unexpected EOF

This is with the dbxcli command utility.

[nightpool]

This is also happening to me with large files.
