I am trying to base64encode a string in a AppSync javascript resolver but as far as I checked, it is not possible nor with btoa() function nor with [js util library](https://docs.aws.amazon.com/appsync/latest/devguide/str-helpers-in-util-str-js.html). Is there any workaround to manage it ?

This is now possible using the [built-in utilities for js](https://docs.aws.amazon.com/appsync/latest/devguide/built-in-util-js.html) ``` util.base64Encode(string) : string ```

How to base64encode in AppSync javascript resolver ?
