AWS SSO Exception

when pointing sleet to a profile with AWS SSO credentials sleet responds with

[System.InvalidOperationException] Assembly AWSSDK.SSOOIDC could not be found or loaded. This assembly must be available at runtime to use Amazon.Runtime.SSOAWSCredentials, AWSSDK.Core, Version=3.3.0.0, Culture=neutral, PublicKeyToken=885c28607f98e604.

for reference, my sleet.json uses "profileName": "aws-dev" and a corresponding entry is in my ~/.aws/config :

[profile aws-dev]
sso_start_url = ...
sso_region = ...
sso_account_id = ...
sso_role_name = ...
region = ...
output = json

I’m getting new credentials with aws sso login --profile aws-dev before, so everything seems to be setup correctly on my side.

Looks like sleet might just need to update it’s dependency on the aws core sdk libraries?

Can confirm, it works! Thanks a lot!

heads up for anyone that comes across this: I initially hit this ArgumentNullException: Parameter name: Options property cannot be empty: ClientName simitlar to https://github.com/aws/aws-sdk-net/issues/1821

I worked through that thread and as it turns out my AWS CLI needed an update as well. After that it worked flawlessly when previously logging in with aws sso login --profile ...

@emgarten Just to explain to you quickly what was throwing there. I went through your code to see what was happening.

First finding: your additions here: https://github.com/emgarten/Sleet/pull/170/files#diff-c5ea30c889009ba11fba4fe02f94c6094f2a031e07b079f92e5c1198f07c3e16R182 are actually not being hit! the SSO Credentials are correctly gotten from line 177 already.

Second:

                            if (credFile.TryGetProfile(profileName, out var profile))
                            {
                                // Successfully created the credentials using the profile
                                var awsCredentials = profile.GetAWSCredentials(profileSource: null);
                                ((SSOAWSCredentials)awsCredentials).Options.ClientName = "SSO";
                                ((SSOAWSCredentials)awsCredentials).Options.SsoVerificationCallback = ssoArgs =>
                                    System.Diagnostics.Process.Start(new System.Diagnostics.ProcessStartInfo()
                                    {
                                        FileName = ssoArgs.VerificationUriComplete, UseShellExecute = true
                                    });
                                amazonS3Client = new AmazonS3Client(awsCredentials, config);
                            }

with this code in place, you will actually handle timed out credentials. You probably would need some considerations to not get a CastException if you have other credentials and I’m not sure if you can start a process form every context where Sleet would run, but that code at least opens the browser for me and does the SSO verification and gets a new token. Without that code, if that ClientName and SsoVerificationCallback is missing, that’s when you get the ArgumentNullException I talked about here.
