listSubscriptionsByTopic not working properly

[cotko]

listSubscriptionsByTopic() does not return the subscription list.
After adding a few subscriptions using sns.subscribe(topicArn, sqsArn) I can get the list of subscriptions using listSubscriptions()
But if I want to only get subsciptions for a specific topic using the listSubscriptionsByTopic, the only data in result is ResponseMetadata, although I see I have subscriptions for the specified topicArn.

@cotko - Can I see your POSTMAN request? I am able to get subscriptions for a topic.

POST: http://localhost:4100
form-data:

Action:ListSubscriptionsByTopic
Version:2012-11-05
TopicArn:arn:aws:sns:local:000000000000:FOO-TOPIC

Response:

<ListSubscriptionsByTopicResponse xmlns="http://queue.amazonaws.com/doc/2012-11-05/">
    <ListSubscriptionsResult>
        <Subscriptions>
            <member>
