Error send file 150MB

 

Hi,

I'm trying to upload a file over 150MB, and I'm using api v2 by the client.Files.UploadSessionStartAsync(body: stream) process, and I always get a message:
Native library pre-loader is trying to load native SQLite library "C:\Users\xx\source\repos\ssxx\xxxx\bin\Debug\x64\SQLite.Interop.dll"...

    A TaskCanceledException can occur if the connection times out. How much data are you attempting to upload in the UploadSessionStartAsync itself? That is, in your "stream" variable? (You mentioned you're attempting to upload a file larger than 150 MB; you should only be sending a part of that in each request though, e.g., in the UploadSessionStartAsync call.)

     

    Also, how long does it take after starting the call before this exception occurs for you? Is there anything that may be interfering with your connection to content.dropboxapi.com?

      I'm sending 30 mega, and it takes 20-30 minutes. Transferring takes a while.

      the exception has been fixed by adding a timeout to requests.

      Using the other batch method, wouldn't the transfer be better and even more agile?

      fragment code:

      var result = await client.Files.UploadSessionStartAsync(body: stream);
      Console.WriteLine("Uploading session id {0}", result.SessionId);

      sessionId = result.SessionId;
      firstShip = false;

      then open session
      ulong offset = Convert.ToUInt64(chunkSize) * Convert.ToUInt64(totalShips);

      UploadSessionCursor cursor = new UploadSessionCursor(sessionId, offset);

      if (readBytes.Length < chunkSize)
      {
      var filePathInDropbox = new CommitInfo(soucedestin, mode: WriteMode.Overwrite.Instance);
      var result = await client.Files.UploadSessionFinishAsync(cursor, filePathInDropbox, null, stream);

      finish
      await client.Files.UploadSessionAppendV2Async(cursor, body: stream);

      Is something going unnoticed?

        Thanks for following up. I'm glad to hear you were able to resolve the exception.

         

        I'm not sure I understand your follow up questions though. Can you clarify? Thanks!
