Bubble Plugin Connection / JSON Formatting

Hello! I am building my first Bubble app and I have a problem that I think/hope should be easy enough to solve for someone with more experience!

The app essentially creates a valuation using an API, calculations etc, that all works smoothly and the data is generated well with the workflows in place. All except for the final step which is to get that data into a PDF.

I have installed the PDFMonkey plugin which looks perfect but when I generate the PDF valuation it only shows my static data, not the dynamic data, even though I have added the fields in the plugin bit. I think from talking to PDFMonkey and of course trusty ChatGPT, it doesn't like the JSON I have put in the workflow plugin bit, but I know nothing about JSON (I'd never even heard of it until a week ago!) so I'm stuck. I don't even know if it's necessary. I have attached a couple of images if it helps.

So I am looking for someone who knows about Bubble and probably JSON as well to just complete that plugin connection for me, ideally as soon as possible. I don't have a big budget which is why I've wasted a week trying to do it myself, but if anyone can help I would be most grateful! Happy to move forward immediately if anyone can work within my budget so please let me know availability.
