I have the following code:

public void ConfigureServices(IServiceCollection services)

 // AWS Options
 var awsOptions = Configuration.GetAWSOptions();
 services.AddDefaultAWSOptions(awsOptions);

 var client = awsOptions.CreateServiceClient<IAmazonDynamoDB>();
 var dynamoDbOptions = new DynamoDbOptions();
 ConfigurationBinder.Bind(Configuration.GetSection("DynamoDbTables"), dynamoDbOptions);

 services.AddScoped<IDynamoDbManager<MyModel>>(provider => new DynamoDbManager<MyModel>(client, dynamoDbOptions.MyModel));


public class DynamoDbManager<T> : DynamoDBContext, IDynamoDbManager<T> where T : class

 private DynamoDBOperationConfig _config;

 public DynamoDbManager(IAmazonDynamoDB client, string tableName) : base(client)
 
 _config = new DynamoDBOperationConfig()
 
 OverrideTableName = tableName
 ;
 

My Appsettings.json is as:

 "AWS": 
 "Region": "us-east-1",
 "AwsId": "xxx",
 "AwsPassword": "xxx"
 ,
 "DynamoDbTables": 
 "MyModel": "MyTable"
 

When I run my code I am getting the error:

AmazonServiceException: Unable to find credentials

Exception 1 of 3:
Amazon.Runtime.AmazonClientException: Unable to find the 'default' profile in CredentialProfileStoreChain. at Amazon.Runtime.FallbackCredentialsFactory.GetAWSCredentials(ICredentialProfileSource source) in E:JenkinsWorkspacesv3-trebuchet-releaseAWSDotNetPublicsdksrcCoreAmazon.RuntimeCredentialsFallbackCredentialsFactory.cs:line 72

Exception 2 of 3:
System.InvalidOperationException: The environment variables AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY/AWS_SESSION_TOKEN were not set with AWS credentials.

Exception 3 of 3:
System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.Http.WinHttpException: The operation timed out
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

I have tried many things but not getting this to work.

I have tried:

Setting up profile as:
Amazon.Runtime.AmazonServiceException: Unable to find credentials

And also tried settingup of environment variables:

https://github.com/aws/aws-sdk-net/issues/499

But still cannot get past this error.

So when we are using AWS SDK we need to setup and provide an AWS access key & a secret key. And from what I have come across it does not read directly from the app settings. So I found below are the two working methods with which you can set these credentials.

Method 1 - Using Credentials file

You can create a credentials file and store your credentials there. Below is the format of the file.

[default]
aws_access_key_id = your id goes here
aws_secret_access_key = your password goes here

In above file, "default" is the name of your profile.

After creating the above file you need to specify the same in Appsettings.json file as:

"AWS": 
 "Profile": "default",
 "ProfilesLocation": "C:\filelocation\awscredentials",
 "Region": "us-east-1",
 

Method 2 - Setting and Reading from Environment Variables

We can setup the environment variables in our startup.cs file as below:

Environment.SetEnvironmentVariable("AWS_ACCESS_KEY_ID", Configuration["AWS:AwsId"]);
Environment.SetEnvironmentVariable("AWS_SECRET_ACCESS_KEY", Configuration["AWS:AwsPassword"]);
Environment.SetEnvironmentVariable("AWS_REGION", Configuration["AWS:Region"]); 

And read these variables from our appSettings.json file as:

AWS": 
 "Region": "us-east-1",
 "AwsId": "xxxx",
 "AwsPassword": "xxxx"
