Hey beam devs,
I am using beam 2.15 and while doing KinesisIO.write() getting a NPE.
This is how I am using it:
KinesisIO.write()
.withStreamName(“streamName")
.withPartitionKey("DEFAULT_PARTITION")
.withAWSClientsProvider(
“A”, “B”, Regions.US_WEST_2)
More specifically
https://github.com/apache/beam/blob/master/sdks/java/io/kinesis/src/main/java/org/apache/beam/sdk/io/kinesis/KinesisIO.java#L685
<https://github.com/apache/beam/blob/master/sdks/java/io/kinesis/src/main/java/org/apache/beam/sdk/io/kinesis/KinesisIO.java#L685>
is failing with NPE
I do see that the producer is transient
private static transient IKinesisProducer producer;
I was wondering if that had do anything with the error below.
