I have been battling with this one issue for about two days now and don't have any solution. I get data back from an API on our old system with regards to Attachments and other data. Now if I run the query in postman, I get the actual document showing up. Now in VS Code, I do the call on the backend in Nodejs and send that data to my frontend, which when I log it to the console gives me the raw data of the file:

What I need help with is in my callback function....how do I get this data in a format where I can just immediately download it with the correct file structure showing. I have really tried quite a few options and nothing seems to work.

Any advice would be greatly appreciated.
