Awesome package. No doubt about it. First of all, Thanks to you a lot.

Here are my config lines...
const config = { babel: { presets: ['@babel/preset-env'] }, wp_textdomain: { src: [ '**/*', '!.git/**', '!node_modules/**', '!.browserslistrc', '!.eslintrc', '!.gitignore', '!gulpfile.js', '!package.json', '!package-lock.json', '!phpcs.xml' ], }, };

Gulp task making...

gulp.task('textdomain', function() { return gulp .src( config.wp_textdomain.src ) .pipe( wptextdomain( '**/*.php', { domain: 'woo-feed', //Specify allowed domain(s) fix: true, keywords: [ //List keyword specifications '__:1,2d', '_e:1,2d', '_x:1,2c,3d', 'esc_html__:1,2d', 'esc_html_e:1,2d', 'esc_html_x:1,2c,3d', 'esc_attr__:1,2d', 'esc_attr_e:1,2d', 'esc_attr_x:1,2c,3d', '_ex:1,2c,3d', '_n:1,2,4d', '_nx:1,2,4c,5d', '_n_noop:1,2,3d', '_nx_noop:1,2,3c,4d' ], })); });

The error shows like below...

please fix it out..
