ECONNRESET while downloading shared file as a stream

Thanks for the report! It looks like the /2/sharing/get_shared_link_file endpoint is configured with a 10 minute timeout. I'll ask the team to look into whether we can increase that.

As a workaround, whether you're using this /2/sharing/get_shared_link_file endpoint or are downloading from the shared link directly, you can use "Range" requests to download a portion of the file at a time.

So if you need to perform these downloads over periods of time longer than the relevant timeout, please use multiple requests lasting no longer than the timeout, to download a piece of the file per request, and then re-assemble the file.

For example, here's a sample of what it would look like in curl:

curl -v -X POST https://content.dropboxapi.com/2/sharing/get_shared_link_file \
  --header 'Authorization: Bearer ACCESS_TOKEN' \
  --header 'Dropbox-API-Arg: {"url":"SHARED_LINK"}' \
  --header 'Range: bytes=0-10'

That would download just the first 11 bytes of the file at the shared link. You can modify the byte range to download any piece of a file, such as to continue downloading the next portion of a file.
