unable to Sub scribing with Mqtt data in AWS IoT core with greengrass deployment

Question

Hi. To publish or to subscribe to IoT Core from a Greengrass component, the recommended way is to use the messaging IPC service: https://docs.aws.amazon.com/greengrass/v2/developerguide/ipc-iot-core-mqtt.html

It is possible to use an MQTT client directly from within a component to connect to IoT Core. The client would have to meet one of the IoT Core [client authentication](https://docs.aws.amazon.com/iot/latest/developerguide/client-authentication.html) methods. Most commonly, an X.509 certificate. IPC is preferred though and takes advantage of the Greengrass core device's existing identity.
