Hi , 

we are getting below error while trying to publish message to Kafka topic .

Conversion of ClipboardPage to GenericRecord has failed. 
org.apache.kafka.common.errors.SerializationException: Error serializing Avro message 
Caused by: java.lang.NullPointerException: null of string in field createdBy of xx.xx.xxx.xxx.xxx.xxxx.LoanApplicationDeniedEvent 
	at org.apache.avro.generic.GenericDatumWriter.npe(GenericDatumWriter.java:183) ~[avro-1.9.1.jar:?] 
	at org.apache.avro.generic.GenericDatumWriter.writeWithoutConversion(GenericDatumWriter.java:177) ~[avro-1.9.1.jar:?] 
	at org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:82) ~[avro-1.9.1.jar:?] 

Avro Schema :

{     "namespace": "xx.xxx.xxx.xxx.xxx.poc",     "type": "record",     "name": "LoanApplicationDeniedEvent",     "doc": "This event is emitted when a loan application is denied after processing.",     "fields": [         { "name": "createdAt", "type": "long"},         { "name": "CaseId", "type": "string"},         { "name": "createdBy", "type": "string", "doc": "The user (human or system) that has denied the loan application" },         { "name": "reason", "type": "string", "doc": "A description of why the loan application was denied" }     ] }

There is no way to create property type as long in pega , so i tried creating createdAt  property as : Double , Integer but got the above serialization error . Even though Data-Set execute step page the 

createdAt property has value (not null).

Any help would be highly appreciated .

Thanks,

Abhishek
