AWS Kinesis InvalidClientTokenId error encountered when using AWS Kinesis.

The provided AWS access key ID does not exist.

Understanding AWS Kinesis

AWS Kinesis is a platform on AWS to collect, process, and analyze real-time, streaming data. It allows developers to build applications that can continuously ingest and process large streams of data records in real-time. Kinesis is commonly used for real-time analytics, log and event data collection, and more.

Identifying the Symptom

When working with AWS Kinesis, you might encounter the InvalidClientTokenId error. This error typically appears when attempting to authenticate or make API calls to AWS services, including Kinesis.

What You Observe

Developers may see an error message similar to the following:

{
"__type": "InvalidClientTokenId",
"message": "The security token included in the request is invalid."
}

Explaining the Issue

The InvalidClientTokenId error indicates that the AWS access key ID provided does not exist or is incorrect. This can happen if the access key ID is mistyped, deleted, or not properly configured in your AWS environment.

Common Causes

  • Incorrect AWS access key ID in your configuration.
  • The access key ID has been deleted or is no longer valid.
  • Misconfigured AWS credentials file or environment variables.

Steps to Fix the Issue

To resolve the InvalidClientTokenId error, follow these steps:

Step 1: Verify AWS Access Key ID

Ensure that the AWS access key ID you are using is correct. You can verify this by checking your AWS Management Console:

  • Log in to the AWS Management Console.
  • Navigate to IAM (Identity and Access Management).
  • Under Access management, click on Users.
  • Select the user associated with the access key.
  • Check the Security credentials tab for the correct access key ID.

Step 2: Update Configuration Files

Ensure that your AWS CLI or SDK configuration files are correctly set up:

[default]
aws_access_key_id = YOUR_ACCESS_KEY_ID
aws_secret_access_key = YOUR_SECRET_ACCESS_KEY

These configurations are typically found in the ~/.aws/credentials file on Linux and macOS, or C:\Users\USERNAME\.aws\credentials on Windows.

Step 3: Check Environment Variables

If you are using environment variables to set your credentials, verify they are correctly set:

export AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY_ID
export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_ACCESS_KEY

On Windows, use the set command:

set AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY_ID
set AWS_SECRET_ACCESS_KEY=YOUR_SECRET_ACCESS_KEY

Step 4: Regenerate Access Keys

If the access key ID is still invalid, consider regenerating your access keys:

  • In the AWS Management Console, navigate to IAM.
  • Select the user and go to the Security credentials tab.
  • Delete the existing access keys and create new ones.
  • Update your configuration files and environment variables with the new keys.

Conclusion

By following these steps, you should be able to resolve the InvalidClientTokenId error when using AWS Kinesis. Always ensure that your AWS credentials are up-to-date and correctly configured to avoid such issues. For more information, refer to the AWS IAM User Guide.
