route53.change_resource_record_sets produces InvalidInput error with valid input

I’m trying update/create a number of DNS records. I’ve limited it to creating one for testing purposes, here is the format of the script I’m using:

#!/usr/bin/env python3

import boto3
import botocore

client = boto3.client('route53')
zone_id = '/hostedzone/ZONEID'

try:
    response = client.change_resource_record_sets(
        HostedZoneId=zone_id,
        ChangeBatch={
            'Changes': [
                {
                    'Action': 'UPSERT',
                    'ResourceRecordSet': {
                        'Name': 'www.example.com',
                        'ResourceRecords': [
                            {
                                'Value': '10.0.0.1'
                            }
                        ],
                        'Type': 'A'
                    }
                }
            ]
        }
    )
    print(response)
except botocore.exceptions.ClientError as e:
    print(e)

I am certain that I’m using the correct HostedZoneId property (the response is the same whether or not I prefix with /hostedzone or not). I am also certain I am using a fully qualified domain for the Name property of the ResourceRecordSet.

I am using Python 3.5.1 and the latest pip3 install of boto3.

The error produced when running the code above as described is An error occurred (InvalidInput) when calling the ChangeResourceRecordSets operation: Invalid request.

It looks like the missing TTL, which is conditionally required based on the docs, is causing the error from Route53’s side. I did something like this to get it working:

import boto3

client = boto3.client('route53')
zone_id = '/hostedzone/ZONEID'

boto3.set_stream_logger('botocore')
response = client.change_resource_record_sets(
    HostedZoneId=zone_id,
    ChangeBatch={
        'Changes': [
            {
                'Action': 'UPSERT',
                'ResourceRecordSet': {
                    'Name': 'www.example.com',
                    'ResourceRecords': [
                        {
                            'Value': '10.0.0.1'
                        }
                    ],
                    'Type': 'A',
                    'TTL': 900
                }
            }
        ]
    }
)

I think the error message could be improved here though. Unfortunately, there is not much we can do from the boto3 side because the error is coming from route53. I would recommend pinging the developer forums to see if this can get updated.

    StartRecordType='A',
