Okay thanks for all your help and replies, right now what I am doing is:

 

    client = ElixirDropbox.Client.new(System.get_env["DROP_BOX_TOKEN"])
    {:ok, file_size} = get_file_size(image_path)
    %{"session_id" => session_id} = ElixirDropbox.Files.UploadSession.start(client, false, image_path)
    ElixirDropbox.Files.UploadSession.finish(client, session_id, upload_image_path, image_path, file_size) |> handle_upload_response

I still got one error as

 

"error_summary\": \"too_many_write_operations/\", \"error\": {\"reason\": {\".tag\": \"too_many_write_operations\"

and 5 errors are API timed out. 

 

I have no idea why still there is too many write operations error? where as I am right now first starting the session, then finishing it in a proper way? 

but these requests almost goes in parallel, should I need to change something as well? more..

In this code I see you're using the 'finish' method, presumably once per file, to finish the uploads. If you send off multiple of these at the same time, you will cause lock contention. 

You should use a single 'finish_batch' to finish multiple file uploads in a single call to avoid this. (Or, only send the multiple 'finish' calls one at a time.)
