--------------------------------------
Summary: Null as default value in avro generates exception
Key: NIFI-7882
URL: https://issues.apache.org/jira/browse/NIFI-7882
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.12.1
Reporter: Dominik Przybysz
When I have a record without value for fields, then missing fields will be
populated with default values from schema. It was added in
https://issues.apache.org/jira/browse/NIFI-4030
But when null is default value then avro 1.8.1 returns
org.apache.avro.JsonProperties$Null which cannot be converted to null value
(the issue in avro is described in
https://issues.apache.org/jira/browse/AVRO-1954)
Probably Apache Nifi should upgrade to newer avro or backport the fix from avro
1.9.x to AvroTypeUtil
