var (
	// ErrInvalidArnPrefix is returned when ARN string format does not start with 'arn'
	ErrInvalidArnPrefix = errors.New("invalid ARN format, must start with 'arn:'")
	// ErrInvalidArnFormat is returned when ARN string format is not valid
	ErrInvalidArnFormat = errors.New("invalid ARN format, must be 'arn:<partition>:<service>:<region>:<accountID>:<resource>'")
