[Bug] Broken Lambda in v2.1.8

[oponomarov-tu]

Observed Behaviour

Updating to v2.1.8 causes the Lambda to fail with the following error:

[ERROR] ParamValidationError: Parameter validation failed: Invalid type for parameter ChangeBatch.Changes[0].ResourceRecordSet.TTL, value: 300, type: <class 'str'>, valid types: <class 'int'> Traceback (most recent call last):   File "/var/task/autoscale.py", line 144, in lambda_handler     process_record(record)   File "/var/task/autoscale.py", line 136, in process_record     process_message(json.loads(record['Sns']['Message']))   File "/var/task/autoscale.py", line 132, in process_message     update_record(zone_id, ip, hostname, operation)   File "/var/task/autoscale.py", line 87, in update_record     route53.change_resource_record_sets(   File "/var/runtime/botocore/client.py", line 530, in _api_call     return self._make_api_call(operation_name, kwargs)   File "/var/runtime/botocore/client.py", line 919, in _make_api_call     request_dict = self._convert_to_request_dict(   File "/var/runtime/botocore/client.py", line 990, in _convert_to_request_dict     request_dict = self._serializer.serialize_to_request(   File "/var/runtime/botocore/validate.py", line 381, in serialize_to_request     raise ParamValidationError(report=report.generate_report())
