  '. ---> Microsoft.BizTalk.Adapter.SftpInvoker.SftpException: Open remote file for read error.

• The adapter "SFTP" raised an error message. Details "System.Exception: Message: Delete file error.. Sftp Error Code: '3221488134'. Sftp Error message: 'The system cannot find the file specified.

Note Error code '3221488139' equals 0xC004020B; error code '3221488134' equals 0xC0040206.

This issue occurs in both Microsoft BizTalk Server 2013 and BizTalk Server 2013 R2.

Cause

This issue occurs because during directory listing (ls), the SFTP adapter (SFTP client) sends the SSH_FXP_OPENDIR packet and expects the SSH_FXP_HANDLE packet according to SFTP version 3. But some servers, for example, Maverick-based servers, send back the SSH_FXP_STATUS (error occurred) packet. The SFTP server is expecting the optional SSH_FXP_REALPATH packet before the OpenDir packet.

Resolution

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
