Error retreiving creds: failed to refresh cached credentials

[SantiRaposo]

Hello,

I'm having some trouble with the way the tool is assuming roles. Given the following configuration file:

# ~/.aws/credentials
[default]
aws_access_key_id=****
aws_secret_access_key=****
aws_session_token="*****"
aws_expiration=****


# ~/.aws/config
[profile example-profile]
role_arn = arn:aws:iam::*:role/example
source_profile=default
role_session_name = user@example.com

I get the following errors when running rain --debug info -p example-profile:

╰─❯ rain --debug info -p example-profile
DEBUG: Getting identity

panic: could not establish AWS credentials; please run 'aws configure' or choose a profile [recovered]
	panic: could not establish AWS credentials; please run 'aws configure' or choose a profile

However the AWS cli works perfectly fine. This does not work even if setting the AWS_PROFILE environment variable.
