Cannot load credentials

I've created owner credentials on ~/.aws/credentials on my mac but it throw an error

> [default]
> aws_access_key_id = MY_ACCESS_KEY_ID
> aws_secret_access_key = MY_SECRET_ACCESS_KEY

```

please help

No source file, entry point, or test is identified. Reproduce the reported macOS setup using ~/.aws/credentials and inspect how the sample initializes the AWS SDK and loads credentials. Done means the sample can authenticate without the reported “Missing credentials in config” error.
