[Bug] Doesn't work with IAM roles

[mbtamuli]

Context

I have a IAM user in account1 and to access resources in account2 I have set up access as described here - IAM tutorial: Delegate access across AWS accounts using IAM roles. I was unable to use cloudlens to access resources in account2, when the same shared configuration and credentials file(~/.aws/config and ~/.aws/credentials) works with AWS CLI.

Expected

cloudlens should deal with shared configuration and credentials similar to AWS CLI/AWS API

Actual

cloudlens is not able to work with profiles which assume roles.

Steps to reproduce

1. Follow the guide - IAM tutorial: Delegate access across AWS accounts using IAM roles to setup the users/roles.
2. Create the following configuration file - ~/.aws/config

   # Credentials specified
   [profile source]
   region=us-east-1
   
   # No credentials
   [profile sandbox-dev]
   region = us-east-1
   role_arn = arn:aws:iam::123456789123:role/S3Admin
   source_profile = source
   

3. Create the following credentials file - ~/.aws/credentials

   [source]
   aws_access_key_id=accessKeyID
   aws_secret_access_key=secretAccessKey
   

cloudlens doesn't even detect the sandbox-dev profile.
