For people using newer versions of the daemon npm module - you need to pass file descriptors instead of strings:

var fs = require('fs');
var stdoutFd = fs.openSync('output.log', 'a');
var stderrFd = fs.openSync('errors.log', 'a');
require('daemon')({
    stdout: stdoutFd, 
    stderr: stderrFd
});
