-------------------------------------
[~ramkychowdary0560] I'm not familiar with `com.wellsfargo.dci.*`, I assume
that is an application that you're working with that makes use of the Kafka
Producer.
Taking a quick look at the implementation of doSend, it appears that it
[implicitly requires the record being sent to be
non-null|https://github.com/apache/kafka/blob/78b4ba7d85a6739ff308ef8d7af678c63ac06ef6/clients/src/main/java/org/apache/kafka/clients/producer/KafkaProducer.java#L993-L995].
You may be passing in a null record, which is not being handled with a more
descriptive error message.
In order to avoid this error, it may be necessary to add a null check of your
own before calling send().
Also, as an aside, you may consider enabling more detailed NPE messages to aid
with your debugging: _-XX:+ShowCodeDetailsInExceptionMessages_
