All, We will work to promptly produce an Apache NiFi 1.9.2 release which will correct a regression introduced in the 1.9.1 release. The issue, NIFI-6150 has been identified and fixed on master and once further testing confirms we're good we'll get the RC going.
I've updated the release guide to discourage use of 1.9.1 until the fix is out. Thanks Joe
