So, using AWS Cognito I created a custom attribute (special_name) which I can access using axios and AWS's Auth.currentUserInfo(). Using my browser's JavaScript console I can see the variable as:

attributes: custom:special_name: 'foo'

Great.

But if I console.log(custom:special_name) I get errors or at best 'undefined'

I'm using Visual Studio Code which really doesn't like the format custom:special_name.

I've already searched on this site and the ideas given, e.g. ['custom: special_name'] also don't work.

I feel like I'm missing something very obvious.

Please put me out of my misery.

Thanks.
