I am trying to deploy a lambda function with greengrass device basically EC2.
Deployment was successful and the lambda function is triggering with the IOT publish event as I want.
But as I can check in logs whenever I published messages on the IOT topic to invoke lambda function, I am getting the below error:
[ERROR] (Thread-3) com.aws.greengrass.mqttclient.MqttClient: Somehow got message from topic that no one subscribed to.
