Amazon rekognition segmentaion response

Question

I have requested for a video segmentation using rekognition tool. The documentation says that the output of the "sqs.receive_message" should be like this:

Response Syntax
{
    'Messages': [
        {
            'MessageId': 'string',
            'ReceiptHandle': 'string',
            'MD5OfBody': 'string',
            'Body': 'string',
            'Attributes': {
                'string': 'string'
            },
            'MD5OfMessageAttributes': 'string',
            'MessageAttributes': {
                'string': {
                    'StringValue': 'string',
                    'BinaryValue': b'bytes',
                    'StringListValues': [
                        'string',
                    ],
                    'BinaryListValues': [
                        b'bytes',
                    ],
                    'DataType': 'string'
                }
            }
        },
    ]
}

But I don't receive such a response. Here is what I always get:

{'ResponseMetadata': {'RequestId': 'xxxxxx', 'HTTPStatusCode': 200, 'HTTPHeaders': {'x-amzn-requestid': 'xxxxxx', 'date': 'Thu, 27 Jan 2022 11:32:58 GMT', 'content-type': 'text/xml', 'content-length': '240'}, 'RetryAttempts': 0}}

Any idea where the problem is?

Hi,

Thank you for using Rekognition Video.

Please follow this example to retrieve SQS message body - https://boto3.amazonaws.com/v1/documentation/api/latest/guide/sqs.html#processing-messages

If you are trying to receive video segmentation job completion notification through SNS+SQS, please follow this documentation for configuring role/permissions - https://docs.aws.amazon.com/rekognition/latest/dg/api-video-roles.html.

The resulted SQS message body (from Rekognition Video) will look like:
```

  "Type" : "Notification",
  "MessageId" : "abcd-efgh-ijkl-mnop",
  "TopicArn" : "arn:aws:sns:us-east-1:123456789012:testsns",
