Can't create Amazon Web Services (AWS) credentials object

Question

I'm trying to get started developing against the local Dynamo DB service. The first step is simply creating a client:

var storedAWSCreds = new StoredProfileAWSCredentials();

This throws an exception:

App.config does not contain credentials information. Either add the AWSAccessKey and AWSSecretKey or AWSProfileName

My app.config has the needed properties:

<add key="AWSProfileName" value="justin"/>
<add key="AWSProfilesLocation" value="C:\code\dynamodb\credentials"/>

The credentials profile file:

justin
aws_access_key_id = REMOVED-FOR-POST
aws_secret_access_key = REMOVED-FOR-POST

At this point I thought I would try one of the other overloaded methods and explicitly tell the constructor what the parameters should be:

var storedAWSCreds = new StoredProfileAWSCredentials("justin", @"C:\code\dynamodb\credentials");

Again, the same exception.

Okay, the exception says I can provide the credentials directly in my config so I tried that:

<add key="AWSAccessKey" value="REMOVED-FOR-POST"/>
<add key="AWSSecretKey" value="REMOVED-FOR-POST"/>

Again, the same exception.

How can I get the StoredProfileAWSCredentials object created? I'm clearly missing something obvious or their exception messages are incorrect.

I will point out, I can create a BasicAWSCredentials object by specifying the access key and secret key in the constructor:

var basicAWSCreds = new BasicAWSCredentials("REMOVED-FOR-POST", "REMOVED-FOR-POST");

But, at some point I would prefer to not have it hard-coded in my application.

Answer 1

Your config section

<add key="AWSProfilesLocation" value="C:\code\dynamodb\credentials" />

should be

<add key="AWSProfilesLocation" value="C:\code\dynamodb\credentials\filename.json" /> 

for it to work. In other words specify the file name in the Profile location.

If you using newer SDK then using the following would work as well:

<configSections>
   <section name="aws" type="Amazon.AWSSection, AWSSDK" />
</configSections>
<aws profileName="YourProfileName" profilesLocation="C:\aws\credentials\aws-credentialfile.json" region="xx-xxxx-x" />

The profile name needs to be in square brackets, like so

[justin]
aws_access_key_id = REMOVED-FOR-POST
aws_secret_access_key = REMOVED-FOR-POST
