Using Route 53 CLI to delete records - json

Question

I'm having trouble using the AWS CLI to delete Route 53 records. I have a list of hundreds of domains and each one needs both 'A' records deleted. I wanted to do this using the CLI to save time, but I can't get the functionality working.
For example, let's say I have the following domain and I want to delete both 'A' records:
I'm using boto3 here, but it is the same AWS CLI API that I can't get working (https://docs.aws.amazon.com/cli/latest/reference/route53/change-resource-record-sets.html). My issue is somewhere in the json filter for this api call:
HostedZoneId='ABC123DEF456',
ChangeBatch={
'Comment': 'deleteing A records for domains',
'Changes': [
{
'Action': 'DELETE',
'ResourceRecordSet': {
'Name': 'example.com',
'Type': 'A',
'Region': 'us-east-1',
'ResourceRecords': [
{
"Value": "1.2.3.4"
}
],
'AliasTarget': {
'HostedZoneId': 'ABC123DEF456',
'DNSName': 'example.com',
'EvaluateTargetHealth': False
}
}
}
]
}
The error I am getting is:
InvalidInput: An error occurred (InvalidInput) when calling the ChangeResourceRecordSets operation: Invalid request: Expected exactly one of [AliasTarget, all of [TTL, and ResourceRecords], or TrafficPolicyInstanceId], but found more than one in Change with [Action=DELETE, Name=example.com, Type=A, SetIdentifier=null]

Answer 1

I think there is some confusion between simple record of A type, and simple record of alias A type. Namely, simple alias record should not don't have ResourceRecords.
To check how they are described in your case, you can use the following command:
aws route53 list-resource-record-sets --hosted-zone-id <your-zone-id>
The output of the above command should be helpful in constructing your DELETE.
Below are examples of outputs from my route53:
simple record
{
"Name": "<simple-a.example.com.>",
"Type": "A",
"TTL": 300,
"ResourceRecords": [
{
"Value": "1.2.3.4"
}
]
}
simple record with alias
{
"Name": "<simple-alias.example.com.>",
"Type": "A",
"AliasTarget": {
"HostedZoneId": "Z06990762X86XLR2ZGTK4",
"DNSName": "<example>.",
"EvaluateTargetHealth": true
}
},
