Hi Zhang, Please find the code snippet.
private ReducingState<NatLogData> aggrRecord; // record being aggregated @Override public void onTimer(long timestamp, OnTimerContext ctx, Collector<NatLogData> out) throws Exception { // FIXME timer is not working? or re-registration not working? NatLogData event = aggrRecord.get(); // Always get null value.

After upgrading to 1.12.3 version, the onTimer method of KeyedProcessFunction is not behaving correctly, the value of ReducingState and ValueState always return null. Could you please help in debugging the issue. Thanks, Suchithra
