AWS SSO With Go SDK Debugging

[karkir0003]

Hey team. Hope you are doing well. I'm trying to use the AWS SDK for Go in order to retrieve secrets from AWS account. I went through the following steps:

1. Setup an User in IAM Identity Center
2. Granted the User a Permission set that allows for retrieval of Secret Value from AWS Secrets Manager
3. In my terminal, I installed AWS CLI latest version
4. I then run aws configure sso and set the session name, permission set role to use, etc
5. I then run export AWS_PROFILE=<sso-profile-name> using the profile name populated in cat ~/.aws/config
6. I then run the Go script shown here
7. I get this error shown in the attached screenshot
   

Could someone please 🙏 help me fix this issue in a way that keeps maintainability in mind, but uses SSO. I don't want to expose/hardcode AWS credentials in this code for security purposes (and my team's Git Guardian cluster would immediately reject such commit). Thanks in advance :)

I confirmed that I have ~/.aws/sso/cache and ~/.aws/config, but not ~/.aws/credentials
