I'm trying to upload an image (PNG) file from URL to the DMP via HTTP POST.
You cannot upload an Asset to the DMP directly using an HTTP POST.
One possible way to display an Asset on the DMP is to display it within a Playlist. To do this via APIs, you must upload the Asset to the DMM, create a Playlist that contains the Asset, and then publish the Playlist to the DMP.

Perhaps I should have made that distinction clear, but I am in fact trying to upload the asset to the DMM using the documented API (/xTAS-core/services/content/assets/content/assets/). Please refer to my original post (endpoint URL):
HTTP POST
Endpoint URL: /xTAS-core/services/content/assets/
Content type: "multipart/form-data"
This is the API that is throwing the HTTP 500 error.
