Boto3 giving empty responses for 'Hourly' Cost Explorer queries

Hi,

I'm trying to use the recently added Hourly billing queries but I can't get it to work with boto3. I have had success using the very latest awscli (1.16.292), but version 1.10.28 of boto3 at least does not appear to work for me.

The query I'm using:

import boto3
from datetime import datetime, timedelta


CURRENT_HOUR = datetime.today().replace(minute=0,second=0,microsecond=0)
PREVIOUS_HOUR = CURRENT_HOUR - timedelta(hours=1)

aws_client = boto3.client(
    'ce',
    aws_access_key_id=AWS_ACCESS_KEY_ID,
    aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
)

response = aws_client.get_cost_and_usage(
        TimePeriod={
            'Start': PREVIOUS_HOUR.isoformat() + 'Z',
            'End': CURRENT_HOUR.isoformat() + 'Z',
        },
        Granularity='HOURLY',
        Metrics=['UNBLENDED_COST'],
        GroupBy=[
            {
                'Type': 'DIMENSION',
                'Key': 'SERVICE'
            },
            {
                'Type': 'DIMENSION',
                'Key': 'LINKED_ACCOUNT'
            }
        ]
    )

Can anyone replicate this?
