GetObjectAsync Method

[Mr0N]

Describe the issue

Will the GetObjectAsync method throw an error if the server sends a 429 error code?

                var content =
                     _client.GetObjectAsync(_config.NameBucket, path).GetAwaiter().GetResult();
                using var stream = content.ResponseStream;
              
                //var buffer = new BufferedStream(stream);

        }

Converting this to Q&A discussion since this is a question.

@Mr0N While Error Responses does not explicitly state the error code 429 (which indicates Too Many Requests), any error returned by S3 service should be handled by S3ErrorResponseUnmarshaller. So you could perhaps try incorporating exponential backoff strategy for handling this exception in your code.
