error when trying to publish

[maniqui]

Hi.
When I run publish p, I'm getting the following error after the site is generated.

Only one files is being uploaded (.htaccess) (which, btw, it's generated by a custom generator hook).
Then, the process fails.

/media/data/sites/example/example.com/node_modules/punch-sftp-publisher/li
b/sftp.js:84
                                        throw err;
                                              ^
