We've been able to consistently reproduce an issue in the KPL where when using multiple credentials for CW metrics/Kinesis access (in our repro, when using an assumed role), the KPL will use the wrong set of credentials when hitting one of the services. This usually manifests itself as a ResourceNotFound, where the stream name can't be found using the CloudWatch account. See below error message for details.
