Logic Apps Standard中Servicebus队列触发器无法使用Content或Message ID属性

环境与流程 #

• 开发工具：Visual Studio Code
• 使用服务：Logic Apps Standard
• 工作流配置：
  • 触发器：Service Bus（应用内）「当队列中有消息可用（peek-lock）」
  • 后续动作：HTTP（调用Beeceptor用于消息调试）

问题现象 #

在HTTP操作中直接引用Content或Message ID属性时，触发模板语言表达式处理错误，错误界面如下：

使用Message ID属性时会出现完全一致的错误。

正常运行场景 #

当HTTP操作中使用Body属性时，流程可正常执行，获取到的消息内容如下：

[{"contentData":"test","userProperties":{"machineName":"xxxxxxxxx","userName":"xxxxx"},"messageId":"439de125-ec06-45c2-9bfa-14a377322cbf","label":"Service Bus Explorer","scheduledEnqueueTimeUtc":"1-1-1970 00:00:00","timeToLive":"14.00:00:00","deliveryCount":1,"enqueuedSequenceNumber":0,"enqueuedTimeUtc":"2024-04-07T11:02:37.774Z","lockedUntilUtc":"2024-04-07T11:03:50.4Z","lockToken":"3bb0c391-d873-4127-9e16-6d43e1aa1168","sequenceNumber":21}]

已尝试的解决方法 #

尝试使用表达式 json(triggerBody()?['contentData']) 来解析内容，但仍然触发与直接使用Content/Message ID属性时相同的错误。
