Hi Dwane,

If possible would you be able to test out the PR here and see if it fixes
your issue? https://github.com/apache/nifi/pull/5727

You can checkout the PR and build the code yourself in the
nifi/nifi-nar-bundles/nifi-solr-bundle/nifi-solr-nar directory or you can
backup your current nifi-solr-nar-1.16.0-SNAPSHOT.nar in the ./nifi/lib
directory and download and replace with the one I built here:
https://easyupload.io/74ujf4.

Thanks,
Nathan
