ShadowManager connection interrupt problem

0

Hi, I am trying to make a deployment to a core device, using ShadowManager, MqttBridge. I have a local MQTT Broker running on the device itself. Here is my deployment configuration: aws.greengrass.Nucleus configuration

{
  "reset": [],
  "merge": {
    "logging": {
      "totalLogsSizeKB": 51200
    },
    "greengrassDataPlanePort": 443,
    "mqtt": {
      "port": 443
    },
    "interpolateComponentConfiguration": true
  }
}

aws.greengrass.ShadowManager

{
  "reset": [],
  "merge": {
    "strategy": {
      "type": "realTime"
    },
    "synchronize": {
      "coreThing": {
        "classic": false,
        "namedShadows": [
          "core-device",
          "applications-shadow"
        ]
      },
      "direction": "betweenDeviceAndCloud"
    }
  }
}

aws.greengrass.clientdevices.mqtt.Bridge

{
  "reset": [],
  "merge": {
    "mqttTopicMapping": {
      "HelloWorldIotCore": {
        "topic": "clients/{iot:thingName}/hello/world",
        "source": "LocalMqtt",
        "target": "IotCore"
      },
      "IotCoreToDevice": {
        "topic": "clients/{iot:thingName}/iotcore/to/device",
        "source": "IotCore",
        "target": "LocalMqtt"
      },
      "ShadowsLocalMqttToIoTCore": {
        "topic": "$aws/things/{iot:thingName}/shadow/#",
        "source": "LocalMqtt",
        "target": "Pubsub"
      },
      "ShadowsIotCoreToLocalMqtt": {
        "topic": "$aws/things/{iot:thingName}/shadow/#",
        "source": "Pubsub",
        "target": "LocalMqtt"
      },
    },
    "brokerUri": "tcp://localhost:1883"
  }
}

GreengrassV2IoTThingPolicy:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "iot:Connect",
        "iot:Publish",
        "iot:Subscribe",
        "iot:Receive",
        "iot:UpdateThingShadow",
        "iot:GetThingShadow",
        "iot:DescribeCertificate",
        "greengrass:*"
      ],
      "Resource": "*"
    }
  ]
}

I see connection interruption logs on greengrass logs as follows. What am I missing ?

Thanks

Hi,

Found the problem. It seems I was trying listen a non-valid topic with MQTTBridge which I missed earlier. In my MqttBrdge configuration there is a topic to listen to, "$testin".

It seems trying to subscribe to this topic causes an interrupt on the connection.

Posting the root cause in case anyone else needs it.

Thanks

Too long for a comment.

After changing IoT Policy as below, I am still getting connection errors. But this time it is a bit different. GreengrassV2IoTThingPolicy:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "iot:*",
        "greengrass:*"
      ],
      "Resource": "*"
    }
  ]
}

Error:
