R4 APIs (Millennium)

Hi,

I'm trying to debug an issue with a Cerner based Healthcare Provider - UAB Hospital

The issue is related to Binary resources, specifically PDF's.
When attempting to request PDF's we're seeing timeouts (even after waiting more than a couple minutes) or 404 errors (XML Binary documents download successfully).

Here's some detailed technical information:

First we requested the DiagnosticReport resource, which has a presentedForm section that looks like the following:

"presentedForm": [
   {
     "contentType": "application/pdf",
     "url": "https://fhir-myrecord.cerner.com/r4/11e960ca-465e-403d-a8ac-REDACTED/Binary/XR-10455279###",
     "title": "REDACTED",
     "creation": "2019-12-16T22:29:43Z"
   },
   {
     "contentType": "application/xml",
     "url": "https://fhir-myrecord.cerner.com/r4/11e960ca-465e-403d-a8ac-REDACTED/Binary/XML-10455279###",
     "title": "REDACTED",
     "creation": "2019-12-16T22:29:43Z"
   }
 ]

When requesting the XML document, we get the following (successful) response:

When requesting any PDF documents, we get client timeouts or 404 errors:

The request for the PDF document looks like the following:

GET /r4/11e960ca-465e-403d-a8ac-REDACTED/Binary/XR-############ HTTP/1.1
Host: fhir-myrecord.cerner.com
Accept: application/fhir+json

As mentioned in https://forums.oracle.com/ords/apexds/post/api-acces-404-error-8625, we are aware that the "Cerner’s Clinical Reporting (XR)" plugin is required if requesting the raw PDF using `application/pdf` content type, however we're using the `application/fhir+json` content type, which should work.

Can you help us determine what's going on?
