What is the problem?

When deploying an example in the official CDK document, EFS creation always fails with the following error:

One or more LifecyclePolicy objects specified are malformed.

After some investigation, I have found that setting both lifecyclePolicy and outOfInfrequentAccessPolicy is the cause of the problem. When you pass only one of them to a construct, it successfully deployed to AWS.

I assume that means CloudFormation template does not allow multiple entries in one LifecyclePolicies item. So, I have not confirmed though, the following changes to emitted CloudFormation template may work.

Bad

"LifecyclePolicies": [
  {
    "TransitionToIA": "AFTER_14_DAYS",
    "TransitionToPrimaryStorageClass": "AFTER_1_ACCESS"
  }
],

Good

"LifecyclePolicies": [
  {
    "TransitionToIA": "AFTER_14_DAYS"
  },
  {
    "TransitionToPrimaryStorageClass": "AFTER_1_ACCESS"
  }
],

Reproduction Steps

Running the example code in the official document

CDK stack source code:

const fileSystem = new efs.FileSystem(this, 'MyEfsFileSystem', {
  vpc: new ec2.Vpc(this, 'VPC'),
  lifecyclePolicy: efs.LifecyclePolicy.AFTER_14_DAYS, // files are not transitioned to infrequent access (IA) storage by default
  performanceMode: efs.PerformanceMode.GENERAL_PURPOSE, // default
  outOfInfrequentAccessPolicy: efs.OutOfInfrequentAccessPolicy.AFTER_1_ACCESS, // files are not transitioned back from (infrequent access) IA to primary storage by default
});

CloudFormation template emitted:

// -- snip --
    "MyEfsFileSystem570A3D32": {
      "Type": "AWS::EFS::FileSystem",
      "Properties": {
        "Encrypted": true,
        "FileSystemTags": [
          {
            "Key": "Name",
            "Value": "CdkTestStack/MyEfsFileSystem"
          }
        ],
        "LifecyclePolicies": [
          {
            "TransitionToIA": "AFTER_14_DAYS",
            "TransitionToPrimaryStorageClass": "AFTER_1_ACCESS"
          }
        ],
        "PerformanceMode": "generalPurpose"
      },
      "UpdateReplacePolicy": "Delete",
      "DeletionPolicy": "Delete",
      "Metadata": {
        "aws:cdk:path": "CdkTestStack/MyEfsFileSystem/Resource"
      }
    },
// -- snip --

What did you expect to happen?

You can successfully deploy EFS even when you set both lifecyclePolicy and outOfInfrequentAccessPolicy.

What actually happened?

Deployment fails with the error message:

One or more LifecyclePolicy objects specified are malformed.
