我正在尝试访问从两 (2) 个 Graph API 调用收到的 JSON 输出中的值,但每次尝试使用它们时都会收到此错误:
表达式评估失败。模板操作 'For_each' 的执行失败:'foreach' 表达式 '@body('Parse_JSON__-_Managed_Devices')?['body']?['value']' 的评估结果是 'Null' 类型。结果必须是有效的数组。
我已经验证我的 Graph API 调用格式正确,并且输出正是我期望从两个 API 调用返回的内容。每次我尝试访问 Azure Runbook 或任何其他逻辑应用任务中解析的 JSON 时都会收到此错误。
我很想知道是否有人以前经历过这种情况以及如何解决?
