No RegionEndpoint or ServiceURL configured
I am writing code to upload files to AWS S3 and receiving this exception:
AmazonClientException: No RegionEndpoint or ServiceURL configured
My code:
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);
The 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?
Solution 1:
The short answer to error...
Amazon.Runtime.AmazonClientException: No RegionEndpoint or ServiceURL configured
...in my case was to specify a region when constructing the client object (for me it was AmazonSimpleEmailServiceClient
).
Assuming you're using BasicAWSCredentials
then try this:
var credentials = new BasicAWSCredentials(accessKeyID, secretKey);
new AmazonS3Client(credentials, RegionEndpoint.USEast1);
// ^^^^^^^^^^^^^^^^^^^^^^ add this
Solution 2:
First of all, you shouldn't hardcode aws credentials.
I had a similar error. Turned out it was due to changes in .Net Core:
One of the biggest changes in .NET Core is the removal of ConfigurationManager and the standard app.config and web.config files
https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-netcore.html
For quick and dirty approach you can create credintial profile file on your machine see https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/setup-credentials.html
e.g. C:\Users\<USERNAME>\.aws\credentials
on Windows
[default]
aws_access_key_id = your_access_key_id
aws_secret_access_key = your_secret_access_key
then in your code you can just do something like:
var dbClient = new AmazonDynamoDBClient(new StoredProfileAWSCredentials(),
RegionEndpoint.USEast1);
A more involved way is: https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-netcore.html#net-core-configuration-builder
public Startup(IHostingEnvironment env)
{
var builder = new ConfigurationBuilder()
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
.AddEnvironmentVariables();
Configuration = builder.Build();
}
appsettings.Development.json
{
"AWS": {
"Profile": "local-test-profile",
"Region": "us-west-2"
}
}
var options = Configuration.GetAWSOptions();
IAmazonS3 client = options.CreateServiceClient<IAmazonS3>();
Solution 3:
In Asp.Net this error can be fixed by adding this line to Web.config:
<add key="AWSRegion" value="us-east-1" />
Worked for me for AWSSDK.SimpleEmail v3.3
