No RegionEndpoint or ServiceURL settings

Question

I am writing code to upload files to AWS S3 and get the following exception:

AmazonClientException: RegionEndpoint or ServiceURL not configured

My code is:

Console.WriteLine("ready to upload");
AWSCredentials credentials;
credentials = new BasicAWSCredentials(accessKeyID.Trim(), secretKey.Trim());
AmazonS3Client s3Client = new AmazonS3Client(accessKeyID.Trim(), secretKey.Trim(), Amazon.RegionEndpoint.USEast1);
Console.WriteLine("Successful verification");
Console.WriteLine("Check if the bucket exists");
if (!CheckBucketExists(s3Client, bucketName))
{
    s3Client.PutBucket(bucketName);
    Console.WriteLine("create bucket");
}
TransferUtility utility = new TransferUtility();
Console.WriteLine("Upload  Directory......");
//exception here
utility.UploadDirectory(@"E:\telerikFile\13ginabdfglil.com", bucketName);

An exception:

Amazon.Runtime.AmazonClientException: No RegionEndpoint or ServiceURL configured
  Amazon.Runtime.ClientConfig.Validate()
  Amazon.S3.AmazonS3Config.Validate()
  Amazon.Runtime.AmazonServiceClient..ctor(AWSCredentials credentials, ClientConfig config)
  Amazon.S3.AmazonS3Client..ctor()
  Amazon.S3.Transfer.TransferUtility..ctor()
  Telerik2Amazon.Program.UploadFile()

What should I do?

Answer 1

Short answer to the error ...

Amazon.Runtime.AmazonClientException: no RegionEndpoint or ServiceURL settings

... in my case, it was necessary to indicate the area when constructing the client object (for me it was AmazonSimpleEmailServiceClient).

Assuming you are using BasicAWSCredentials, try the following:

var credentials = new BasicAWSCredentials(accessKeyID, secretKey);

new AmazonS3Client(credentials, RegionEndpoint.USEast1);

//                              ^^^^^^^^^^^^^^^^^^^^^^  add this

Asp.Net , Web.config:

<add key="AWSRegion" value="us-east-1" />

Answer 4

TransferUtility() :

var credentials = new BasicAWSCredentials(accessKeyID, secretKey);

var S3Client = new AmazonS3Client(credentials, RegionEndpoint.USEast1);

this._transferUtility = new TransferUtility(S3Client);
