本指南說明如何編寫自訂記錄和錯誤訊息,協助排解 Workspace Studio「活動」分頁中無法執行的步驟。
根據預設,「活動」分頁會記錄步驟名稱,如資訊清單檔案中所定義。為協助您瞭解步驟執行期間發生的情況,您也應為步驟編寫自訂記錄。如果使用者在執行步驟時遇到非預期行為,記錄檔可協助他們瞭解發生了什麼事。
實用的記錄項目有兩項屬性:
- 這個方塊包含步驟建立或更新的資源超連結。舉例來說,如果步驟會建立 Google 文件,請使用這個資訊方塊連結至建立的 Google 文件。
- 詳細錯誤訊息,說明步驟無法執行的原因,以及如何解決問題。
下列程式碼範例說明 onExecuteFunctionCreateDocument() 如何將成功執行和錯誤記錄到「活動」分頁。
