stepfunctions-tasks: mwaa service generates wrong action in role policy

[tam0ri]

Describe the bug

Following code is properly creates a step in Step Functions

const listEnvs = new sfn_tasks.CallAwsService(stack, 'ListMWAAEnvironments', {
  service: 'mwaa',
  action: 'listEnvironments',
  resultPath: sfn.JsonPath.DISCARD,
  iamResources: ['*'],
});

However, it creates wrong statement in the role policy.

        {
            "Action": "mwaa:listEnvironments",
            "Resource": "*",
            "Effect": "Allow"
        }

Correct service prefix for MWAA is airflow.
https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonmanagedworkflowsforapacheairflow.html

Amazon Managed Workflows for Apache Airflow (service prefix: airflow) provides the following service-specific resources, actions, and condition context keys for use in IAM permission policies.

This issue is similar with #27573.

Expected Behavior

Action should be airflow:listEnvironments

Current Behavior

Action is mwaa:listEnvironments

Reproduction Steps

Sample code for reproduction is below:

import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import {
  aws_stepfunctions as sfn,
  aws_stepfunctions_tasks as sfn_tasks,
} from 'aws-cdk-lib';

export class SfnMwaaStack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const listEnvs = new sfn_tasks.CallAwsService(scope, 'ListMWAAEnvironments', {
      service: 'mwaa',
      action: 'listEnvironments',
      resultPath: sfn.JsonPath.DISCARD,
      iamResources: ['*'],
    });
  
    new sfn.StateMachine(this, 'SimpleStateMachine', {
      definitionBody: sfn.DefinitionBody.fromChainable(listEnvs)
    });
  }
}

Possible Solution

Adding mwaa into iamServiceMap. I'll submit PR later.

aws-cdk/packages/aws-cdk-lib/aws-stepfunctions-tasks/lib/aws-sdk/call-aws-service.ts

Lines 92 to 95 in 25ee8ef

	const iamServiceMap: Record<string, string> = {
	sfn: 'states',
	cloudwatchlogs: 'logs',
	};
