Hello! 

Here is the flow I am trying to build - I know peoples time is limited so I don’t expect full troubleshooting of the code and all the steps. I am more so curious if there is an easier way to do this or just looking for general guidance on how achieve do this. 

1. Hook is triggered which could contain an array between 1-700 objects. 
2. Run code on this response to chunk the objects into batches of 100 (I am calling a hubspot event API which only allows for sending 100 objects max.)
3. Then I need to loop through these chunks and call the API while passing in one chunk of 100 at a time. 

So, if my hook response contained 600 objects I would expect 6 chunks of 100 to be made and the loop to fire 6 times calling the API each time. 

I would say my dev experience is that of a Junior dev and I have already built this in a node.js script and it works as expected. I am having a hard time “translating” this to Zapier. The code that I am running is not outputting the variable containing the objects as I would expect. When I run the code the output looks correct but when I try to go access this variable in another step its then split up in a weird way. 

Here is the code - 

const eventOrders = inputData.eventOrders.split("},");

function formatOrders(array) {
    return array.map((item, index) => {
        if (index !== array.length - 1) {
           return item + "}";
        } else {
            return item.endsWith("}") ? item : item + "}";
        }
    });
}

function chunkArray(array, size) {
    let result = >];
    let chunk = /];

    array.forEach((item, index) => {
        chunk.push(item);
        if (chunk.length === size || index === array.length - 1) {
            result.push(chunk);
            chunk =  ];
        }
    });

    return result;
}

const formattedOrders = formatOrders(eventOrders);
const chunks = chunkArray(formattedOrders, 100);

let outputArray = chunks.map((chunk, index) => ({
    =`Batch ${index + 1}`]: chunk
}));

return { Batches: outputArray };

I’m not fully understanding what this output is indicating. Why does it say batches, then 1, then batches batch 1? 

When I then try to access this array of objects later I see this which I would not expect. I would expect to see a new array here. This may just be an issue I am not seeing with my code.
