NetSuite Server Side SS2.x Script to upload files to Dropbox - body encoding issue

Hi team

I'm trying to upload a file to Dropbox via the API using a user event (server side) script in NetSuite.

I can get a file to be uploaded, but having an issue with the "body" encoding.

Thus far, my https request looks like:

URL and headers:

and the body is being set as follows:

var httpsRequest = {
                    method: https.Method.POST,
                    url: request.url,
                    headers: request.headers,
                    body : data.content,
                };

data.content is the file from the NS file cabinet, extracted with myfile.getContents().

When loading the file it looks like Base64.

I have also tried re-encoding the file contents to (UTF_8 to Base64), but the file is still unreadable when synced to the desktop.

If i do the request from Postman to Dropbox it works, then when I change the URL to a request.bin, the working "body" is structured like:

However, when coming from NetSuite, the same data looks like:

So I'm not sure how I set the "body" in my NetSuite request to be received in the same way?

Any help would be much appreciated, and save what little hair I have left.
