Passing multiple arguments is deprecated! Pass an options object instead

I use gulp4 when I run 'data' task I'll get the warning: WARNING!! Passing multiple arguments is deprecated! Pass an options object instead.

// Build data json
gulp.task('data', () => {
    return 
      gulp.src([ '**/*.yml', '!**/_*.yml' ], 
      { cwd: 'source/modules/*/data' })
        .pipe($.plumber(options.plumber))
        .pipe($.yaml({ space: '\t' }))
        .pipe($.mergeJson('data.json'))
        .pipe(gulp.dest('tmp'));
});

If I remove .pipe($mergeJson), the warning won't notify What am I missing?
