Template react app, handling post payload in the server file.

[cnfloss]

I don't know if what I am asking to do is out of the scope of what is possible for the solution I whipped up.  But basically I want to resize/manipulate product images and then upload them to shopify.  I got everything to work on postman, when I copy and paste a base64 encoded attachment it works, but I cannot pass data for my front end to my server.  I have no clue what I am missing and why I can't find the payload.  I had the data fields as body for the front end, I'll update that but I am really really stuck and would appreciate any guidance.  Do I need to do something different to even accept payloads from the frontend?
