security token invalid exception from aws dynamodb- .net core sdk

Question

I am trying to insert records in dynamodb using AWS .NET core SDK, but I am getting following exception:

The security token included in the request is invalid.

Please find below the steps I have done to connect it:

1. Created a new access key in IAM.
2. downloaded access key and secret key locally.
3. created a file name credentials in C:/users//.aws/

4. Added following code to the file (removed credentials for security purpose)

   [default] aws_access_key_id = xxxxxxxxxxxxxxxxxxxx aws_secret_access_key = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

5. Added following code to appsettings.json file:

   "AWS":{ "Region": "ap-south-1", "Profile": "default"}

6. in startup.cs, ConfigureServices method I have added following code: services.AddDefaultAWSOptions(Configuration.GetAWSOptions()); services.AddAWSService<IAmazonDynamoDB>();

7. When I execute my code using following piece for code, I receive exception "The security token included in the request is invalid"

8. I have also tried the getting accesskey and secret key from appsettings.json "AWS": { "Region": "ap-south-1", "AccessKey": "xxxxxxxxxxxxxxxxxxxx", "SecretKey": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" }

9. And Setting these credentials in environment variables in startup.cs file

services.AddDefaultAWSOptions(Configuration.GetAWSOptions());
services.AddMvc(); Environment.SetEnvironmentVariable("AWS_ACCESS_KEY_ID", Configuration["AWS:AccessKey"]); Environment.SetEnvironmentVariable("AWS_SECRET_ACCESS_KEY", Configuration["AWS:SecretKey"]); Environment.SetEnvironmentVariable("AWS_REGION", Configuration["AWS:Region"]); services.AddAWSService<IAmazonDynamoDB>();

10. I still get the same exception, please find the stack trace below:

Can someone help me with this problem?

Please let me know if I am missing anything here.

Answer 1

Here, verify your access key ID & secret access key for selected profile in AWS Explorer. Because of false credential in profile this issue is created. or if you don't need profile any more than remove it.
