             Summary: Avro Writer Schema Default Value not correctly being set
                 Key: NIFI-9629
                 URL: https://issues.apache.org/jira/browse/NIFI-9629
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.15.3, 1.15.2, 1.15.1, 1.15.0, 1.16.0
         Environment: WSL Ubuntu, Java 11 Open JDK
            Reporter: Nathan English
         Attachments: Avro_Default_Value_Conversion_Issue_-_20220125.xml

Using the Avro Record Set Writer to create fields that don't exist and set default values is currently causing issues. I haven't tested all the possible types, but below are the ones I have tested:
 * String with string default value - OK
 * String with null - {color:#FF0000}Error{color}
 * Byte with null - {color:#FF0000}Error{color}
 * Int with 0 Default value - OK
 * Long with 0 default value - {color:#FF0000}Error{color}

{color:#172b4d}Looking at the AvroTypeUtil class when the field is put with its default value the null, is actually an org.apache.avro.JsonProperties$Null instead of an actual null value. The long is actually a default of an int value. These both throw errors when being encoded to the Avro Format.{color}

{color:#172b4d}The attached flow successfully reproduces the errors.{color}

 

{color:#172b4d}I have tested the flow and it successfully works in v1.12.1, but not a build from the main branch.{color}

 

{color:#172b4d}This issue leads on from NIFI-9594{color}
