Update. seems like EphemeralStorage property has not been included in the Lambda service's read handler.... The results of calling the [get-function](https://docs.aws.amazon.com/cli/latest/reference/lambda/get-function.html) on a Function does NOT include the EphemeralStorage property.

Similar to [#1296](https://github.com/aws-cloudformation/cloudformation-coverage-roadmap/issues/1296)

Similar to [ cfn cli fails to install following the provided instructions #864 ](https://github.com/aws-cloudformation/cloudformation-cli/issues/864)

**Workaround** After some tinkering, found the following combination works for me. ``` pip install --upgrade requests urllib3 pip install markupsafe==2.0.1 pyyaml==5.4.1 pip install werkzeug==2.1.2 --no-deps ```

Seems related to: - [Drift Detection false positive for KmsKeyId property under AWS::EFS::FileSystem resource #1219 ](https://github.com/aws-cloudformation/cloudformation-coverage-roadmap/issues/1219) - [Drift dectection with property KmsKeyId: alias/example-key-alias #994 ](https://github.com/aws-cloudformation/cloudformation-coverage-roadmap/issues/994)

Confirmed. Issue still persists, recommend reopening ticket for further consideration.

Just retested, confirmed issue still relevant. Recommend re-opening this ticket ``` key = kms.Key(self, "MyKey", removal_policy=RemovalPolicy.DESTROY, ) cluster = CfnCluster(self, 'Cluster', cluster_type='single-node', db_name='dev', master_username='bevelvoerder', master_user_password='Wagw00rdEen', node_type='dc2.large', encrypted=True, kms_key_id=key.key_id, classic=True, )...

Similar issue as https://github.com/aws-cloudformation/cloudformation-coverage-roadmap/issues/1204

Confirmed. This behavior is consistently reproducible. The '[classic](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-redshift-cluster.html#cfn-redshift-cluster-classic)' property is reporting false-positive drift, regardless of the value. Test code: > key = kms.Key(self, "MyKey", > removal_policy=RemovalPolicy.DESTROY, > ) > >...

Confirmed here too. ``` file_system = efs.FileSystem(self, "MyEfsFileSystem", vpc=vpc, lifecycle_policy=efs.LifecyclePolicy.AFTER_14_DAYS, # files are not transitioned to infrequent access (IA) storage by default performance_mode=efs.PerformanceMode.GENERAL_PURPOSE, # default out_of_infrequent_access_policy=efs.OutOfInfrequentAccessPolicy.AFTER_1_ACCESS, removal_policy=RemovalPolicy.DESTROY, ) volume_one =...
