FHIR Server OAUTH2 with Microsoft Entra Intersystems Health 2025.3

I am working on setting up OAUTH with FHIR and Microsoft Entra.  I have configured the Client and configured it in the FHIR Server successfully. However, I get 401 when authenticating with a token.   Looking at ^ISCLOG I see:
^ISCLOG("Data",9,0)="accessToken=<jwt token>, scope=, aud="
^ISCLOG("Data",10)=$lb(3,"OAuth2","[OAuth2.ServerDefinition:ValidateJWT]","171430","%SYS","2026-04-28 17:41:25.305549397","OAuth2.ServerDefinition.1","","zwKKakZZZx2")
^ISCLOG("Data",10,0)="JWT valid? sc=1"
^ISCLOG("Data",11)=$lb(3,"HSFHIRServer","[HS.FHIRServer.RestHandler:OnPreDispatch]CSP Request","171430","HEALTHSHARE","2026-04-28 17:41:25.30613001","HS.FHIRServer.RestHandler.1","","zwKKakZZZx2")
^ISCLOG("Data",11,0)="Content-Type: , Secure: 1, $Username: UnknownUser"
Any Suggestions on what the issue might be?
