go-wkhtmltopdf | Golang commandline wrapper for wkhtmltopdf | Document Editor library

What I'm trying to implement is this:

1. User sends query parameters from React FE microservice to the Django BE microservice.
   • URI is something like /api/reports?startingPage=12&dataView=Region
   • These PDFs are way too big to be generated in FE, so doing it server side
2. Request makes its way into the view.py where the data related to dataView=Region is queried from the database, each row is iterated through and a PDF report is generated for each item
   • Each dataView=Region can consist of a few hundred items and each of those items is its own report that can be a page long or several pages long
3. As the reports are generated, they should be saved to the server persistent volume claim and not be sent back to FE until they have all run.
4. When they have all run, I plan to use pypdf2 to combine all of the PDFs into one large file.
5. At that point, the file is sent back to the FE to download.

I'm only working on 1. and 3. at this point and I'm unable to:

1. Get the files to save to storage
2. Prevent the default behavior of the PDF being sent back to the FE after it has been generated

The PDFs are being generated, so that is good.

I'm trying to implement the suggestions as found here, but I'm not getting the desired results:

Save pdf from django-wkhtmltopdf to server (instead of returning as a response)

This is what I currently have on the Django side:

i create a service to generate pdf file with go-wkhtmltopdf

this is the function
