Missing path in file options

[majabee]

Module Versions: node: 7.2.1 npm: 3.10.10 gulp: 3.9.1 gulp-concat: 2.6.1 gulp-sourcemaps: 2.2.1

When I´m running my gulp concat task i get this error message:

[21:34:18] Starting 'concatjs'... [21:34:18] 'concatjs' errored after 15 ms [21:34:18] Error: gulp-concat: Missing path in file options at module.exports (/Users/xx/yy/sites/projects/gulptest/node_modules/gulp-concat/index.js:32:11) at Gulp.

my gulpfile looks like this:

var concat = require('gulp-concat');
var sourcemaps = require('gulp-sourcemaps');

gulp.task('concatjs', function() {
  return gulp.src([
    './src/core/scripts/vendor/source1.js',
    './src/core/scripts/vendor/source2.js'
  ])
  .pipe(sourcemaps.init())
  .pipe(concat(['global.js'], {newLine: ';'}))
  .pipe(sourcemaps.write())
  .pipe(gulp.dest('./build/scripts'));
});

gulp.task('default', ['concatjs']);

What can I do to solve this and what is the problem.

concat('global.js', {newLine: ';'}) not concat(['global.js'], {newLine: ';'}) - the argument is a string not an array
