Adobe Document Generation API - Persistent Server Error

Hello,

I've been working on developing a few documents for use in the Adobe Document Generation API. Until yesterday I was able to use it with no issues, and had integrated a separate document into a Power Automate workflow with zero issues. However now I am running into a problem where any new documents I create throw an error when I try to generate them.

In order to narrow the issue down I've edited the tags, checked JSON, and still run into the same problem.

In my tests I've discovered that it now occurs on every document template I create regardless of content, including the previous templates which were functioning. As an example, I created a new test document, implemented a single tag as the only content, and attempted to generate with basic JSON (Please see example below).

Tesst JSON data:

Document Template:

Attempt Document Generation:

Since this issue cropped up, even the documents that were running fine in my Automate Flow two days ago are running into the error.

Any help would be greatly appreciated!
