Add support for AWS SSO

OK!

Unless you passed in --s3-profile then opt.Profile will be empty.

Can you try

  • your patch with Profile: "" - this should pick up AWS_PROFILE
  • and can you try the original code with --s3-profile my-sso-profile-name
	// Overrides the config profile the Session should be created from. If not
	// set the value of the environment variable will be loaded (AWS_PROFILE,
	// or AWS_DEFAULT_PROFILE if the Shared Config is enabled).
	//
	// If not set and environment variables are not set the "default"
	// (DefaultSharedConfigProfile) will be used as the profile to load the
	// session config from.
	Profile string

	// Instructs how the Session will be created based on the AWS_SDK_LOAD_CONFIG
	// environment variable. By default a Session will be created using the
	// value provided by the AWS_SDK_LOAD_CONFIG environment variable.
	//
	// Setting this value to SharedConfigEnable or SharedConfigDisable
	// will allow you to override the AWS_SDK_LOAD_CONFIG environment variable
	// and enable or disable the shared config functionality.
	SharedConfigState SharedConfigState

So either there is a bug in the SDK not picking up AWS_PROFILE or there is a bug with the configuration chain loader...
