boto3 s3 head_object method is returning Storage class as None

Code:

import boto3

s3_cli = boto3.client('s3')
object_summary = s3_cli.head_object(
        Bucket='test-cf',
        Key='RDS.template',
        VersionId='szA3ws4bH6k.rDXOEAchlh1x3OgthNEB'
    )

print('LastModified: {}'.format(object_summary.get('LastModified')))
print('StorageClass: {}'.format(object_summary.get('StorageClass')))
print('Metadata: {}'.format(object_summary.get('Metadata')))
print('ContentLength(KB): {}'.format(object_summary.get('ContentLength')/1024))

Output:

LastModified: 2017-06-08 09:22:43+00:00
StorageClass: None
Metadata: {}
ContentLength(KB): 15

Am unable to get the StorageClass of the key using boto3 sdk. I can see the storage class set as standard from the aws console. I have also tried using s3.ObjectSummary and also s3.ObjectVersion methods in boto3 s3 resouces, but they also returned None.

Not sure why it is returning None. Meanwhile, use the following code to get the storage class. Let me check my version of Boto3.

bucket = s3.Bucket('test-cf')
for object in bucket.objects.all():
  print object.key, object.storage_class
