Getting “Shard map update for stream xxx” failed using Amazon KPL: (AWSErrorMarshaller)Encountered Unknown AWSError

Question

I'm trying to write to an Amazon Kinesis Firehose using the KPL library. Despite my best efforts, every attempt to connect and write to the library results in the following log lines:

I am able to get a client connected and sending data using the standard AWS Client.

Here is how I'm creating the client.

       KinesisProducerConfiguration config = new KinesisProducerConfiguration()
            .setCredentialsProvider(credentials.getTemporaryCredentialsProvider())
            .setKinesisEndpoint("firehose.us-west-2.amazonaws.com")
            .setRegion(awsConfig.getRegion());

    KinesisProducer kinesisProducer = new KinesisProducer(config);

Answer 1

I was attempting to connect KPL to a firehose. I have just discovered that this is not supported. Lord knows why not.
