Mencatat aktivitas dan error

Panduan ini menjelaskan cara menulis log dan pesan error kustom yang membantu memecahkan masalah langkah yang gagal dijalankan di tab Aktivitas Workspace Studio.

Secara default, tab Aktivitas mencatat nama langkah yang berjalan seperti yang ditentukan dalam file manifesnya. Untuk membantu Anda memahami apa yang terjadi selama menjalankan langkah, Anda juga harus menulis log kustom untuk langkah Anda. Jika pengguna mengalami perilaku yang tidak terduga saat menjalankan langkah Anda, log Anda dapat membantu mereka memahami apa yang terjadi.

Entri log yang bermanfaat memiliki dua atribut:

  • Chip yang berisi hyperlink ke resource yang dibuat atau diperbarui oleh langkah tersebut. Misalnya, jika langkah Anda membuat Google Dokumen, gunakan chip untuk menautkan ke Google Dokumen yang dibuat.
  • Pesan error mendetail yang menjelaskan alasan langkah gagal dijalankan dan cara menyelesaikan masalah.

Contoh kode berikut menunjukkan cara onExecuteFunctionCreateDocument() dapat mencatat keberhasilan dan error ke tab Aktivitas.

Berikut adalah file manifes:
