If you want to consume content from an API that is an array or JSON and don’t like to have it converted to a meaningless junk of text, it will be almost impossible with the API Connector plugin.
But If you have access to the API (your AWS Lambda Gateway) you can change the output of the array to text by using JSON.stringify and then to use it in your Bubble.is Google Chart s, you convert it back to an array by using JSON.parse().
