AWS SQS error when sending message.

[LeifEirik]

Hi all,

I'm getting an error when sending a AWS SQS message. The error I get is:
{
"error": {
"code": "AmazonClientException",
"message": "No RegionEndpoint or ServiceURL configured"
}
}

My code for sending the message:

  const
    AWS_ACCESS_KEY = 'My_AWS_ACCESS_KEY';
    AWS_SECRET_KEY = 'My_AWS_SECRET_KEY';
    AWS_MT_QUEUE   = 'https://sqs.us-east-1.amazonaws.com/MyQueue/ICCMT.fifo';

  procedure SendSQS;
  begin
    lClient := TAmazonSQSClient.Create(AWS_ACCESS_KEY, AWS_SECRET_KEY);
    lClient.Config.RegionEndpoint := TRegionEndpoints.USEast1;

    lMessageRequest := TSendMessageRequest.Create;
    lMessageRequest.MessageBody := '{"client_message_id":12345,"imei":"123456789012345","message":"0123456789ABCDEF"}';
    lMessageRequest.QueueUrl := AWS_MT_QUEUE;
    lMessageRequest.MessageGroupId := TGUID.NewGuid.ToString;
    lMessageRequest.MessageDeduplicationId := TGUID.NewGuid.ToString;

    lMessageResponse := lClient.SendMessage(lMessageRequest);
  end;

PS. When I run the code from my development enviroment on a seperate VMWARE machine, the code actually works just fine and sends the messsage as expected. But when I move my executable over to my Windows server on my production enviroment, it fails with the error message mentioned above.

Any hint or help greatly appricated.

Is it some type of firewall issue ?

Try this:

    lClient := TAmazonSQSClient.Create(AWS_ACCESS_KEY, AWS_SECRET_KEY, TRegionEndpoints.USEast1);

And of course, for production environments, never put access key and secret key directly in code.

Thank you, that worked!

Not sure though if I understand the difference between the none working code:

  lClient := TAmazonSQSClient.Create(AWS_ACCESS_KEY, AWS_SECRET_KEY);
  lClient.Config.RegionEndpoint := TRegionEndpoints.USEast1;

...and the code that works:

  lClient := TAmazonSQSClient.Create(AWS_ACCESS_KEY, AWS_SECRET_KEY, TRegionEndpoints.USEast1);

Config is immutable after the client is created. If you want a complex config, you should create the config and then pass it in the constructor of the client.
