Our team was standing up a new instance of Sitecore XP1 10.1 and noticed that anytime you loaded Experience Profile, you got a nice error about “An error has occurred”. Digging into the XHR posts, there’s a big fat 500 response from the Contact Search API:

Exception calling GetService() - Service Type: "ContactsController"
 System.InvalidOperationException: Unable to resolve service for type 'Sitecore.Xdb.ReferenceData.Core.IReferenceDataClient' while attempting to activate 'Sitecore.Marketing.Operations.Xdb.ReferenceData.Service.Definitions.Profiles.ProfileDefinitionReferenceDataRepository'.

This means it’s time to go check out the XConnect Search Indexer. Lo and behold, there are some errors:

2021-04-21 15:50:54.054 +00:00 [Warning] Exception calling GetService() - Service Type: "ContactsController"
 System.InvalidOperationException: Unable to resolve service for type 'Sitecore.Xdb.ReferenceData.Core.IReferenceDataClient' while attempting to activate 'Sitecore.Marketing.Operations.Xdb.ReferenceData.Service.Definitions.Profiles.ProfileDefinitionReferenceDataRepository'.

Won’t lie, I’ve seen that error a ton of times. Someone forgot to define a Service in the Dependency Injection front. Since we hadn’t done any customization of the code at this point, and since that error really looks like a file issue, we reached out to support. Their response? Looks like Sitecore missed enabling some config files in the XP1 topology. They told us to enable the following:

App_Data\Config\Sitecore\ReferenceData\sc.XConnect.ReferenceData.Core.Initialize.xml.disabled
App_Data\Config\Sitecore\ReferenceData\sc.XConnect.ReferenceData.Service.Initialize.xml.disabled
App_Data\Config\Sitecore\ReferenceData\sc.XConnect.ReferenceData.SqlServer.Initialize.xml.disabled

And we did. And it was fixed. Happens to the best of us. Hope this saves you some debugging time 🙂
