Receive Empty Messages SQS

[alaglil]

I use FIFO Queue and , I get an empty result in receiveMessage function, thanks for your help

 $result = $sqs->sendMessage(new SendMessageRequest([
                    'QueueUrl' => $queueUrl,
                    'DelaySeconds' => 0,
                    'MessageGroupId' =>  'report',
                    'MessageDeduplicationId'  =>  $clientId
                    'MessageBody' => 'mesage test',
];

  $result = $sqs->receiveMessage(new ReceiveMessageRequest([
        'QueueUrl' => $queueUrl,
        'AttributeNames' => [MessageSystemAttributeName::MESSAGE_GROUP_ID, MessageSystemAttributeName::MESSAGE_DEDUPLICATION_ID],
        'WaitTimeSeconds' => 20,
        'VisibilityTimeout' => 20,
        'MaxNumberOfMessages' => 1, 
        'MessageAttributeNames' => ['All']
    ]));

I found the problem I have a lambda SQS trigger function which calls a php endpoint which has its role of receiving the messages, as indicated above, the lambda function deletes the messages before it arrives in the endpoint I'm a little lost what is the best way to call the receiveMessages function automaticly and process them ?

I'm closing the issue because there is no bug in the SDK. The purpose of SQS message is to be delivered once to a single consumer, If you have concurrent applications (lambda + PHP) that consumes the same queues, you can not predict which one will get the message.
