I am using boto3 to put data in Kinesis data stream. The code is running successfully and returns response with 200 status. But when I check the data in AWS console, am not able to see the recently added data with TRIM_HORIZON configuration.

Have configured a KDS which will receive events from EventBus. In target rule of bus, while configuring the input transformers, have not defined any partition key for KDS. The KDS receives the data from bus.
