Failed loading x509 data without error detail about edgex-examples HOT 2 CLOSED

This issue is caused by certs not found, so i add a line in the dockerfile
COPY --from=builder /aws-export/certs /certs
the "Failed loading x509 data" issue disappeared, but i still can not see any logs shows MQTT message sent success.

below is my log, MQTT not sent success but I cannot find any error logs in the docker log.

from edgex-examples.

The reason for this problem is that the pipeline stopped, in the third function "printAWSDataToConsole", the return is both false, so the SDK will not continue calling successive function in the pipeline which is "MQTTSend" in this case.
