Hi, I am testing AWS Injector and it works great for Kinesis data stream and DynamoDB. However, when testing with Kinesis Firehose I see this error: java.lang.ClassCastException: class com.cirruslink.ingest.kinesis.KinesisFirehoseIngestService cannot be cast to class com.cirruslink.ingest.kinesis.KinesisIngestService (com.cirruslink.ingest.kinesis.KinesisFirehoseIngestService and com.cirruslink.ingest.kinesis.KinesisIngestService are in unnamed module of loader com.inductiveautomation.ignition.gateway.modules.ModuleClassLoader @6345e2cc)

Can you please advise if this is issue with version 4.0.21 (b2024012618). Thanks.

Hmmm - this looks like it could be a regression. We’re looking into it and will get back to you on this thread.
