cdcr replicator NPE errors

Hi,
I am frequently seeing cdcr-replicator null pointer exception errors in the
logs.
Any suggestions on how to address this?
*Solr version: 7.7.2*

ExecutorUtil
Uncaught exception java.lang.NullPointerException thrown by thread:
cdcr-replicator-773-thread-3
java.lang.Exception: Submitter stack trace

People with @apache.org email addresses can readily join the ASF 
workspace, I do not know whether it is possible for others.  That 
workspace might be only for ASF members.

https://the-asf.slack.com

In that workspace, there is a lucene-solr channel and a solr-dev channel.

Thanks,
Shawn
