Errors

Exceptions are raised on error responses. Each service defines its own exception types, all descending from a common base. For example:

try
  SQS.SendMessage(QueueUrl, 'Hello');
except
  on E: ESQSNonExistentQueue do
    Writeln('Queue not found');
  on E: ESQSException do
    Writeln('SQS error: ', E.Message);
end;

Some errors are automatically retried with exponential back-off. By default the SDK will retry up to 3 times before raising the exception. See Automatic Retries for configuration options.
