無法使用 python 為 azure 數據工廠中的每個活動創建

Question

我正在嘗試使用 python 創建 azure 數據工廠管道和資源。 我在某些 ADF 活動（如查找、復制 ..）方面取得了成功，但我在這里面臨的問題是我正在嘗試使用 FOR Each 活動將幾個表從 SQL 復制到 blob，它拋出以下錯誤

您將如何在內部為每個活動創建活動？ 非常感謝任何輸入。 謝謝！

參考： https : //docs.microsoft.com/en-us/python/api/azure-mgmt-datafactory/azure.mgmt.datafactory.models.foreachactivity? view = azure- python

活動需要是活動列表，而您正在傳遞一個。 嘗試創建一個列表並將復制活動添加到其中，並在活動參數中傳遞該列表。
