Bryan Bende commented on NIFI-6886:
-----------------------------------

I mentioned this in Slack, but also mentioning here to ensure it is seen...

{color:#1d1c1d}If you can enable DEBUG logging in logback.xml for this package {color}{{org.apache.nifi.remote.client}}{color:#1d1c1d} it would produce a stacktrace to go with that WARNING, and it would be very helpful for someone debugging this.{color}

> WARNING
> *SiteToSiteBulletinReportingTask[id=843df3f5-016e-1000-15f0-c32647b2a675] org.apache.nifi.remote.client.PeerSelector@48a5201e Unable to refresh Remote Group's peers due to null*
> This log appears in nifi-app.log too.
> Try to debug this error, I figure out that has a new PeerSelector implementation in version 1.10.0 and the error occurs when it tries to save the Peers State.
