(redshift): modifyClusterIamRoles with unexpected key 'DefaultIamRoleArn' found in params

[clementy-aws]

What is the problem?

The Lambda code

const AWS = require('aws-sdk');
const redshift = new AWS.Redshift();

exports.handler = async event => {
    const clusterId = event.ResourceProperties.ClusterIdentifier;
    const roleArn = event.ResourceProperties.RoleArn;

    var data = await redshift.describeClusters({ ClusterIdentifier: clusterId }).promise();
    if (data.Clusters.length != 1) {
        throw new Error(`Unable to find cluster ${clusterId}`);
    }

    console.log(`Set this role as default ${roleArn}`)
    await redshift.modifyClusterIamRoles({
         ClusterIdentifier: clusterId,
         DefaultIamRoleArn: roleArn
    }).promise();
    console.log(`Cluster ${clusterId} default role set.`)
};

The error log:

Also tried the following CLI:

aws redshift modify-cluster-iam-roles \
--cluster-identifier ${CLUSTER_ID} \
--default-iam-role-arn ${ROLE_ARN}

It complains:

Unknown options: --default-iam-role-arn, 

Where I have:

clementy@ cdk-redshift % aws --version
aws-cli/2.2.42 Python/3.8.8 Darwin/20.6.0 exe/x86_64 prompt/off

Reproduction Steps

As explained in the above section.

What did you expect to happen?

The default role of redshift should be properly set.

What actually happened?

See the exception in the first section.
