Konfigurasi Sistem Magento 2 untuk masalah Modul

Saya mengunjungi banyak situs untuk mencari solusi masalah ini.

Tetapi setelah membuat system.xmldan acl.xmlMagento memberi saya laporan yang dihasilkan kesalahan.

Kesalahan

a: 4: {i: 0; s: 140: "Pemberitahuan: Indeks tidak terdefinisi: id di / usr / local / ampps / www / mgn2 / vendor / magento / module-config / Model / Config / Struktur / Elemen / Iterator. php on line 59 "; i: 1; s: 6391:" # 0 /usr/local/ampps/www/mgn2/vendor/magento/module-config/Model/Config/Structure/Element/Iterator.php(59) : Magento \ Framework \ App \ ErrorHandler-> handler (8, 'Indeks tidak ditentukan ...', '/ usr / local / ampp ...', 59, Array)

Bisakah Anda mengklarifikasi masalah ini?

Anda system.xmlganti ini

<tab>HelloWorldMVVM</tab>

dengan ini

<tab>Pulsestorm</tab>
