      Description

      A null attribute value (as you would see for a removed attribute) causes the provenance repo to thrown an NPE here:

      https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-provenance-repository-bundle/nifi-persistent-provenance-repository/src/main/java/org/apache/nifi/provenance/PersistentProvenanceRepository.java#L1789

      (as "entry.getValue()" is null...)

      suggested fix is to change:

      if (entry.getValue().length() > maxAttributeChars) {

      to:

      if (entry.getValue() != null && entry.getValue().length() > maxAttributeChars) {
