POST requests to nodejs server always leaves body empty

Why is the data I put in the custom object not sent? My server console.logs req.body and its always an empty object.

I need to integrate my nodejs server for my app, is this even possible? If so, how do you send info in the body object? I can’t find any hint of this issue anywhere.

Would I be able to just send the request by inserting js into a function? I really just want to use the front-end builder.
