Vinyl-ftp strange error - gulp

Question

I am using Vinyl-ftp to do deployment, when i try to connect with FileZilla or Total Commander everything works ok, but when i try wirh Gulp task i got strange error, i dont see the difference, here is my Gulp task and error message
gulp.task('ftp-test-connection', function () {
var conn = ftp.create({
host: 'hostname',
user: 'user',
password: 'password',
parallel: 10,
log: gutil.log
});
var globs = [
'./styles/**/*{css,png,jpg,gif,ttf,woff,eof,svg,woff2}',
'./images/**',
'./views/**',
'./scripts/vendor.scripts.min.js',
'./dist/index.html',
'./dist_test/main.scripts.min.js',
'./dist_test/web.config'
];
return gulp.src(globs, { base: '.', buffer: false })
.pipe(gulpIf('dist/index.html', rename({ dirname: '' })))
.pipe(gulpIf('dist/web.config', rename({ dirname: '' })))
.pipe(gulpIf('dist_test/main.scripts.min.js', rename({ dirname: '/scripts' })))
.pipe(conn.newer('/site/wwwroot'))
.pipe(conn.dest('/site/wwwroot'));
});
And here is my error

Answer 1

I faced the same issue with "vinyl-gulp" and Azure App Services (a.k.a. Azure Web Sites).
In my case the problem was caused by the "\" character contained on the Azure FTP username.
I just had to double the "\" (ex: "someuser\$someuser") to solve the issue.
I hope it helps...
