Since installing March 2023 SU, we are seeing these errors in our Exchange 2019 servers.

Unhandled Exception "Object reference not set to an instance of an object."
Stack trace: at Microsoft.Exchange.AutoDiscoverV2.FlightSettingRepository.GetHostNameFromVdir(ADObjectId serverSiteId, String protocol)
at Microsoft.Exchange.AutoDiscoverV2.AutoDiscoverV2.ExecuteOnPremEndFlow(AutoDiscoverV2Request request)
at Microsoft.Exchange.AutoDiscoverV2.AutoDiscoverV2.Execute(AutoDiscoverV2Request request, ITenantRepository tenantRepository)
at Microsoft.Exchange.AutoDiscoverV2.AutoDiscoverV2HandlerBase.<>c__DisplayClass11_0.<ProcessRequest>b__0()
at Microsoft.Exchange.Common.IL.ILUtil.DoTryFilterCatch(Action tryDelegate, Func`2 filterDelegate, Action`1 catchDelegate)

 

The error is not in our Exchange 2013 servers (soon to be decomissioned)

I am aware of the article https://support.microsoft.com/en-us/topic/autodiscover-event-id-1-after-installing-exchange-server-2019-cu3-or-exchange-server-2016-cu14-93850e62-4cf4-8a76-5fd4-c8ce6f032015 but as this pertains to CU3 of Exchange 2019, want to check before making any changes that it pertains to this situation.
