Can't find element in SVG file

[alienlebarge]

I'm trying to change fill color of an SVG.

gulp.task('colors', function() {
  return gulp.src("./src/logo.svg")
    .pipe(xeditor([
      {path: '//g[@id="logo-color"]', attr: {'fill': '#FFFFF'}}
    ]))
    .pipe(gulp.dest('./dest'));
});

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg width="311px" height="522px" viewBox="0 0 311 522" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:sketch="http://www.bohemiancoding.com/sketch/ns">
    <!-- Generator: Sketch 3.4 (15575) - http://www.bohemiancoding.com/sketch -->
    <title>logo</title>
    <desc>Created with Sketch.</desc>
    <defs></defs>
    <g id="Logo" stroke="none" stroke-width="1" fill="none" fill-rule="evenodd" sketch:type="MSPage">
        <g id="logo-color" sketch:type="MSArtboardGroup" fill="#3C8A2E">
          ... 
        </g>
    </g>
</svg>

But I'm always getting this error:

events.js:85
      throw er; // Unhandled 'error' event
            ^
Error: Can't find element at "//g[@id="logo-color"]"

Do not see what I'm doing wrong. Can somebody help me ?
