URL: https://github.com/apache/camel-kafka-connector/issues/1268
Hi I'm new to apache camel and I was getting the following error when trying
to run the kinesis sink connector on a kafka topic:
```
Caused by: java.lang.NullPointerException

```
I did some digging around and see it is related to [this
issue](https://github.com/apache/camel-kafka-connector/issues/1261).
I found [the excellent
tutorial](https://github.com/apache/camel-kafka-connector-examples/tree/main/aws2-kinesis/aws2-kinesis-sink)
that passes in headers when we write to a kafka topic, eg. ` echo "hello
there" | ./kafkacat -b localhost:9092 -H
"CamelHeader.CamelAwsKinesisPartitionKey=partition-1" -t mytopic` and indeed it
works if I do that.
I am guessing that these headers are needed for the internal routing in
Camel, but we absolutely won't have these headers on our kafka topics. I don't
know how and where to set these headers. Do I need to define a SMT or
something? I'm not sure where in the documentation I need to look to understand
this. Grateful for any pointers, thanks.
