This is the underlying error:

This error only occurs in prod. I can pull the content of the page using: https://<url>/api/episerver/v2.0/content/<id>?expand=*. The content returns for the page, but when I use the block ID to pull that data, it gives me a 502. Any ideas on what's going wrong here?

Following up, the error only seems to occur when I place blocks in folders. I tried a few different folders and they all fail. But if I place the block in the “for this page” folder, it works fine. Is there some sort of security or setup that needs to be changed here?

Are you sending the correct header.  Is your content in en or en-us?

I'm not sending anything there. It only errors when the blocks are in a folder. If it's in the "for this page" folder, it works fine. and works fine in int and staging
