AWS Python SDK | Route 53 - Deleting a Resource Record

Question

How to delete a DNS record in Route 53? I followed the documentation , but I still can't get it to work. I don’t know that I missed something here.

Based on the documentation:

DELETE: deletes the existing set of resource records that has the specified values ​​for Name, Type, SetIdentifier (for delays, weighted, geolocation, and set of fault tolerance resource records) and TTL (except for the alias of the set of resource records for which the TTL defines the AWS resource to which you forward DNS queries).

But I always get this error:

Traceback (most recent call last):

botocore.exceptions.ClientError: An error occurred (InvalidInput) when calling the ChangeResourceRecordSets operation: Invalid request 

Here is my code:

#!/usr/bin/env python3


import boto3

r53 = boto3.client('route53')
zone_id = 'ABCDEFGHIJKLMNO'
record = 'me.domain.com'
r_type = 'CNAME'
r_val = 'google.com'


def del_record():
    response = r53.change_resource_record_sets(
        HostedZoneId=zone_id,
        ChangeBatch={
            'Changes': [
                {
                    'Action': 'DELETE',
                    'ResourceRecordSet': {
                        'Name': record,
                        'Type': r_type,
                        'TTL': 300
                    }
                }
            ]
        }
    )

    return response


def main():
    print(del_record())

if __name__ == '__main__':
    main()

ResourceRecordSet ResourceRecords, "target" .

    HostedZoneId=zone_id,
    ChangeBatch={
        'Changes': [
            {
                'Action': 'DELETE',
                'ResourceRecordSet': {
                    'Name': record,
                    'Type': r_type,
                    'TTL': 300,
                    'ResourceRecords': [
                        {
                            'Value': target
                        }
                    ]
                }
            }
        ]
    }
