AWS Kinesis InvalidParameterValue error encountered when making a request to AWS Kinesis.

What is AWS Kinesis InvalidParameterValue error encountered when making a request to AWS Kinesis.

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 often used for real-time analytics, log and event data collection, and more.

Identifying the Symptom

When working with AWS Kinesis, you might encounter the InvalidParameterValue error. This error typically surfaces when a request is made with an invalid parameter value. The error message will usually indicate which parameter is causing the issue.

Common Scenarios

Incorrect data type for a parameter. Parameter value out of the allowed range. Missing required parameters.

Details About the InvalidParameterValue Issue

The InvalidParameterValue error is a client-side error that indicates a parameter in your request does not meet the expected criteria. This could be due to incorrect data types, values that are out of range, or other specification mismatches.

Example Error Message

{ "__type": "InvalidParameterValueException", "message": "The parameter 'ShardCount' is invalid."}

Steps to Fix the InvalidParameterValue Issue

To resolve the InvalidParameterValue error, follow these steps:

1. Review the AWS Kinesis API Documentation

Ensure that you are using the correct parameter names and values as specified in the AWS Kinesis API Reference. Pay special attention to the data types and value ranges.

2. Validate Parameter Values

Check the values you are passing to the API. For example, if you are setting the ShardCount, ensure it is a positive integer within the allowed range. Use the AWS CLI or SDKs to validate your requests:

aws kinesis create-stream --stream-name my-stream --shard-count 2

3. Use AWS SDKs for Parameter Validation

Consider using AWS SDKs which can help with parameter validation and provide more informative error messages. For example, using the AWS SDK for Python (Boto3):

import boto3client = boto3.client('kinesis')try: response = client.create_stream( StreamName='my-stream', ShardCount=2 )except client.exceptions.InvalidParameterValueException as e: print("Error: ", e)

4. Check for Updates or Changes

Ensure that there have been no recent changes to the AWS Kinesis service or API that might affect your parameters. Regularly check the AWS Release Notes for updates.

Conclusion

By carefully reviewing the parameters and ensuring they meet the required specifications, you can resolve the InvalidParameterValue error in AWS Kinesis. Always refer to the official AWS documentation for the most accurate and up-to-date information.
