OIC Gen3 fails to parse SCIM Users response with URN-based attributes (Unbound prefix: urn)

Hi Team,

I’m facing an issue when consuming the SCIM Users API from Oracle HCM in OIC Gen3. My use case is very simple: I only need to retrieve the displayName of a user based on their email.

Example request:

GET /hcmRestApi/scim/Users?filter=emails eq "user@email.com"&attributes=displayName

However, the response still includes SCIM extension attributes with URN-based keys, such as:

{  "schemas": [    "urn:scim:schemas:core:2.0:User",    "urn:scim:schemas:extension:fa:2.0:faUser"  ],  "displayName": "User Name",  "urn:scim:schemas:extension:fa:2.0:faUser": {    "userCategory": "****"  }}

When invoking this endpoint via the REST Adapter, OIC fails during response processing with errors like:
