Getting Error(No RegionEndpoint or ServiceURL configured) on EC2 instance even if IAM roles are setup in .net web application

Question

I've configured IAM roles for my different services on EC2 server.with the help of below link IAM Role Setup. According to AWS docs after setting IAM role we don't need any credentials to be stored in our application it takes the credential details from EC2 instance metadata. However, I am getting error when I removed AWS key from my web.config."No RegionEndpoint or ServiceURL configured" After some time when I added region point entry to my Web.config entry then it started working.

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

Please note in another application where I am accessing only AWS DynamoDB on the same server, it works without adding region point entry in config. Any kind of help is appreciated.Thank you in advance.

IAM role is only for fetching credentials from the metadata server, not for the region you are trying to connect to. So, you have to specify the region in the config file, not the credentials. Some services default to a region (like us-east-1) but many services expect the region to be configured or passed when creating a client object.
