We're trying to SFTP a small text file and receive the output below. We don't know what "Error 10" is. Can anyone enlighten us?

According to SFTP v4 draft, error code 10 is SSH_FX_NO_SUCH_PATH and means that "the file path does not exist or is invalid". This error was reported by the SFTP server in response to client's attempt to open the file.

In most cases, the SftpException would contain an error message sent by the server. In this case, however, the server only send a code with an empty message ('' in the log), so a simple "Error 10" message was reported instead. We will change our code to report something more meaningful in this case.

Thanks Lukas for verifying that. I saw code 10 (here) and thought as much but I wasn't sure if the SftpException used the same codes or it was something internal to the assembly. It turns out our partner has not given us rw on the drop point.

Actually, SftpException has Code property which returns an SftpErrorCode enum value that represents the SFTP error code. However, we convert all codes to SFTP v3 error numbers (in order to make the component behave the same regardless the SFTP server), of which there are only 9.
