Permission denied while ploading a file

Version: 2016.1.0.0

Issue: We have a scenario where we download the file from clients SFTP server and put it in s3 and append something to that and overwrite the existing file in SFTP. While uploading the file we are seeing this issue of permission denied.

I tried uploading the file manually through filezilla and it works without issues.

Error Details:

Message: Permission Denied.

Stack Trace:

at Renci.SshNet.Sftp.SftpSession.RequestOpen(String path, Flags flags, Boolean nullOnError)\n at Renci.SshNet.SftpClient.InternalUploadFile(Stream input, String path, Flags flags, SftpUploadAsyncResult asyncResult, Action`1 uploadCallback)\n at

I would like know

Why this is happening?
Will there be a scenario where the SFTP transfer works with filzilla but not using SSH.NET?
How to capture the messages from SSH.NET programatically?

Commencez par reproduire l’upload de SftpClient décrit dans l’issue et examinez les entrées de pile RequestOpen et InternalUploadFile. Comparez le transfert avec SSH.NET au transfert réussi avec FileZilla et déterminez comment capturer les messages de SSH.NET par programmation ; le travail est considéré comme terminé lorsque la cause de la différence de permissions a été identifiée et que la sortie de diagnostic pertinente a été documentée.
