How to use DynamoDB export_table_to_point_in_time boto3?

Question

I got error when trying to use IncrementalExport which fail the validation for "ExportType" and "IncrementalExportSpecification". I'm using the latest boto3 1.28.79. I follow the documentation here

client.export_table_to_point_in_time(
            TableArn=table_arn,
            S3Bucket=s3_bucket_name,
            ExportFormat='DYNAMODB_JSON',
            ExportType='INCREMENTAL_EXPORT',
            IncrementalExportSpecification={
                'ExportFromTime': datetime.today(),
                'ExportToTime': datetime.today() - timedelta(days=1),
                'ExportViewType': 'NEW_IMAGE'
            }
        )

Error:

Using the latest version of boto3==1.28.79, botocore==1.31.79. I was able to export the data with no issue:

import boto3
from datetime import datetime
from datetime import timedelta

dynamodb = boto3.client('dynamodb')
table_arn = 'arn:aws:dynamodb:eu-west-1:<account-id>:table/<my-table>'
s3_bucket_name = 'my-bucket'
from_time = datetime.today() - timedelta(days=1)
to_time = datetime.today()
try:
    dynamodb.export_table_to_point_in_time(
                TableArn=table_arn,
                S3Bucket=s3_bucket_name,
                ExportFormat='DYNAMODB_JSON',
                ExportType='INCREMENTAL_EXPORT',
                IncrementalExportSpecification={
                    'ExportFromTime': from_time,
                    'ExportToTime': to_time,
                    'ExportViewType': 'NEW_IMAGE'
                }
            )
except Exception as e:
    print(e)
