Bug: Invalid type for ApiGatewayAuthorizerRequestV2 parser model

[leandrodamascena]

Expected Behaviour

Original issue: aws-powertools/powertools-lambda-typescript#3483

The identitySource field in ApiGatewayAuthorizerRequestV2 can be None when the Lambda authorizer is not configured with an identity source.

Current Behaviour

Its always considering a List with at least 1 record, but can be None.

Code snippet

import json
from aws_lambda_powertools.utilities.parser import parse
from aws_lambda_powertools.utilities.parser.models import ApiGatewayAuthorizerRequestV2

def lambda_handler(event, context):
    parsed_event = parse(model=ApiGatewayAuthorizerRequestV2, event=event)
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }

Possible Solution

Add Optional.

Steps to Reproduce

1 - Deploy the code below
2 - Invoke the Lambda with a valid payload from API GW HTTP Authorizer v2

Powertools for AWS Lambda (Python) version

latest

AWS Lambda function runtime

3.13

Packaging format used
