Hi @CloutKhan! Thanks for opening this issue. This is actually not a bug, what is happening here is because you are using SQSEvent in your function signature but you are not using the @event_source decorator, so we are not able to convert your dict to an object. Check if this works with the code below:

from aws_lambda_powertools.utilities.data_classes import event_source, SQSEvent
from aws_lambda_powertools.utilities.typing import LambdaContext

@event_source(data_class=SQSEvent)
def lambda_handler(event: SQSEvent, context: LambdaContext):
    for record in event.records: # where event["Records"] does not fail.
        pass

thanks
