我们正在尝试从运行在EC2实例上的Java程序中读取Amazon SQS队列.有时,我们得到一个com.amazonaws.AbortedException.我们的代码如下所示:
AmazonSQSClient sqs = new AmazonSQSClient(myCredentials);
ReceiveMessageRequest request = new ReceiveMessageRequest()
.withWaitTimeSeconds(20)
.withMaxNumberOfMessages(1)
.withQueueUrl(queueUrl);
ReceiveMessageResult result = sqs.receiveMessage(request);
我们的堆栈跟踪如下所示:

at …我正在尝试在 AWS CloudFront 上上传公钥。我生成密钥如下
ssh-keygen -t ecdsa -b 521
我也尝试过
ssh-keygen -b 4096
当我通过控制台上传它时，出现以下错误： com.amazonaws.services.cloudfront.model.InvalidArgumentException：您的请求包含空/无效/超出限制的 RSA 编码密钥（服务：AmazonCloudFront；状态代码：400；错误代码：InvalidArgument；请求 ID：08fa98af-0c02-11ea-b06e-d771d01bbfcb）
结果ssh -V是“OpenSSH_7.7p1，OpenSSL 1.0.2p 14 Aug 2018”。
任何帮助，将不胜感激。谢谢。
