Put Content Update Giving 415 Error

[JERREN EVERY]

Hello, I am trying to do something similar compared to the link below. https://confluence.atlassian.com/confkb/using-the-confluence-rest-api-to-upload-an-attachment-to-one-or-more-pages-1014274390.html

I have uploaded the Image via the post call.

I have retrieved the page info as it exists and appropriately automated the update of version number and inclusion of the reference to the image. 

When I try to update the content of the page via the Put call I get a 415 error. I am confused as to what this endpoint expects as far as receiving this content. I have tried multiple things without luck.
