AWS Kinesis is a platform on AWS to collect, process, and analyze real-time streaming data, allowing you to get timely insights and react quickly to new information. It is commonly used for real-time analytics, log and event data collection, and processing.
When working with AWS Kinesis, you might encounter the KMSNotFoundException error. This error typically occurs when you attempt to use a KMS key that AWS Kinesis cannot find. The error message usually states that the specified KMS key does not exist.
While trying to encrypt data streams or configure encryption settings, you receive an error message indicating that the KMS key is not found. This prevents you from proceeding with your encryption configuration.
The KMSNotFoundException is an error that occurs when the AWS Key Management Service (KMS) key specified in your Kinesis configuration is not found. This can happen if the key ID is incorrect, the key has been deleted, or the key is in a different AWS region than your Kinesis stream.
To resolve the KMSNotFoundException, follow these steps:
Ensure that the KMS key ID or ARN you are using is correct. You can list your KMS keys using the AWS CLI:
aws kms list-keys --region
Check the output to confirm that the key ID matches the one you are using in your Kinesis configuration.
Ensure that the KMS key is not deleted or disabled. You can describe the key to check its status:
aws kms describe-key --key-id --region
Look for the KeyState in the output. It should be Enabled.
Ensure that the KMS key is in the same region as your Kinesis stream. KMS keys are region-specific, and you must use a key from the same region as your Kinesis stream.
For more information on AWS KMS and managing keys, refer to the AWS KMS Developer Guide. To learn more about configuring encryption for Kinesis, visit the Kinesis Data Streams Encryption Documentation.
