The edge publishes somehow publishes payloads that are valid but empty i.e;
Payloads contain timestamp and a valid seqnum, but the metrics section is empty;

NDATA

{"timestamp":1619874081095,"metrics":[],"seq":218}

Replication: Set GenerateDataTimer to e.g. T#60s whilst keeping publishPeriod to e.g. 500

1) Find root cause of this unwanted and unnecessary sending of empty payloads,
2) Suggest and implement a suitable fix.
