記錄活動和錯誤

本指南說明如何編寫自訂記錄和錯誤訊息,協助您在流程「活動」分頁中,排解無法執行的流程步驟問題。

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步驟的 onExecuteFunction() 如何將成功執行和錯誤記錄到「活動」分頁:

Apps Script

function onExecuteFunctionCreateDocument(e) {

  // true if the document is successfully created, false if something goes wrong.
  var successfulRun = createDocument();

  // If successful, return an activity log linking to the created document.
  if (successfulRun == true) {
    return {
      "hostAppAction": {
        "workflowAction": {
          "returnOutputVariablesAction": {
            "variableValues": [
              {}
            ],
            "log": {
              "textFormatElements": [
                {
                  "text": "Created Google Doc"
                },
                {
                  "chip": {
                    "icon": {
                      "materialIconName": "edit_document"
                    },
                    "url": "https://docs.google.com/document/d/{DOCUMENT}",
                    "label": "{NAMEOFDOCUMENT}"
                  }
                },
                {
                  "text": "Created doc detailing how to improve product."
                }
              ]
            },
            "trigger_log": {
              "textFormatElements": [
                {
                  "text": "Email log "
                }
              ]
            }
          }
        }
      }
    };
  }

  // Otherwise, return an activity log containing an error explaining what happened and how to resolve the issue.
  else {
    return {
      "hostAppAction": {
        "workflowAction": {
          "returnElementErrorAction": {
            "errorActionability": "NOT_ACTIONABLE",
            "errorRetryability": "NOT_RETRYABLE",
            "error_log": {
              "textFormatElements": [
                {
                  "text": "Failed to create Google Doc"
                },
                {
                  "chip": {
                    "icon": {
                      "materialIconName": "document"
                    },
                    "label": "{NAMEOFDOCUMENT}"
                  }
                },
                {
                  "text": "Unable to create Google Document because OAuth verification failed. Grant one of these authorization scopes and try again: https://www.googleapis.com/auth/documents, https://www.googleapis.com/auth/drive, https://www.googleapis.com/auth/drive.file"
                }
              ]
            }
          }
        }
      }
    };
  }
