Hello, trying to create an EKS cluster with a managed node group using EKS crosswalk for AWS, I get a strange error which doesn’t speak to me. Here is the code

cluster, err := eks.NewCluster(ctx, "test",
	&eks.ClusterArgs{
		ProviderCredentialOpts: &eks.KubeconfigOptionsArgs{
			RoleArn: pulumi.String("<arn>"),
		},
		CreateOidcProvider:   pulumi.Bool(true),
		SkipDefaultNodeGroup: pulumi.Bool(true),
	},
)
if err != nil {
	return fmt.Errorf("failed to create EKS cluster: %w", err)
}

_, err = eks.NewManagedNodeGroup(ctx, "ng1",
	&eks.ManagedNodeGroupArgs{
		Cluster: cluster.Core,
	},
)
if err != nil {
	return fmt.Errorf("failed to create EKS managed node group: %w", err)
}

and here is the error

Previewing update (test):

    error: program failed: waiting for RPCs: marshaling properties: awaiting input property cluster: expected a ec2.SecurityGroup, got a resource of type ec2.SecurityGroup
    exit status 1
 
    error: an unhandled error occurred: program exited with non-zero exit code: 1

Do you know what this error means? Should I post this message in #aws instead?
