Introduction

Working with AWS Lambda and self-managed Kafka clusters can be a powerful combination. However, setting up the event source mapping correctly is crucial, and any misconfiguration may lead to frustrating errors. One common issue is encountering the error message: "Unsupported block type: self_managed_kafka_event_source_config" when using the aws_lambda_event_source_mapping resource.

In this guide, we will explore this error in detail and provide a clear solution to get your configuration back on track.

Understanding the Problem

If you are receiving the aforementioned error, it typically indicates that the Terraform version you are using does not recognize the self_managed_kafka_event_source_config block in your aws_lambda_event_source_mapping resource. This can occur if you are running an outdated version of the AWS provider plugin.

Example Scenario

Consider a configuration where you want to set up a mapping for AWS Lambda to listen to a self-managed Kafka cluster. However, when you try to define the self_managed_kafka_event_source_config block, it throws an error similar to this:

The Solution: Upgrade AWS Provider

To solve the issue, you need to upgrade your AWS provider to a version that supports the specified configuration.

Step-by-Step Guide to Upgrade

Check Current Provider Version: Identify the version of the AWS provider you are currently using. You can do this by looking in your .tf files indicating the provider or by checking the Terraform state.

Update the Provider Version: Modify your provider block in either your main Terraform configuration file or in your specific module file. Make sure the provider version is set to at least 5.18.1. Here’s an example:

Conclusion

By upgrading your AWS provider to version 5.18.1 or higher, the self_managed_kafka_event_source_config block becomes valid within the aws_lambda_event_source_mapping resource. Remember, keeping your Terraform providers up to date is crucial to utilizing the latest features and configurations offered by AWS.

If you follow these steps, you should be able to successfully set up your AWS Lambda event source mapping without running into the unsupported block type error.
