Azure IoT中下层设备温度传感器模块消息上传至上层设备的路由配置问题

我正在构建IoT设备层级架构，需要让上层设备接收子设备发送的消息。我尝试在上层设备的deployment.json文件中，通过配置BrokeredEndpoint作为输入路由来实现需求，相关配置如下：

上层设备（deployment.json 路由配置） #

"routes": {
  "pythondepmoduleToIoTHub": "FROM /messages/modules/pythondepmodule/outputs/* INTO $upstream",
  "sensorTopythondepmodule": "FROM /messages/modules/childdeviceModule/outputs/output INTO BrokeredEndpoint(\"/modules/pythondepmodule/inputs/input1\")"
}

下层设备路由配置 #

"routes": {
  "childdeviceModuleToIoTHub": "FROM /messages/modules/childdeviceModule/outputs/* INTO $upstream",
  "sensorTochilddeviceModule": "FROM /messages/modules/SimulatedTemperatureSensor/outputs/temperatureOutput INTO BrokeredEndpoint(\"/modules/childdeviceModule/inputs/input1\")"
}
