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

[Cross-linking for reference: https://stackoverflow.com/questions/64454739/using-server-side-ss2-x-to-upload-files-to-dropbox-body-encoding-issue ]

I can't offer help with the NetSuite side of things, as that's not made by Dropbox, but for reference, the /2/files/upload Dropbox API endpoint is a "content-upload" style endpoint, meaning it expects the file data in the HTTPS request body. The data should be sent just as a raw octet-stream (per the "Content-Type"), without any additional encoding. (Dropbox doesn't perform any additional operations, such as encoding/decoding, on the received data before storing it.)

So, for example, if your data source is giving you your file data encoded with base64 encoding, you may need to base64-decode it before sending it to Dropbox.
