NotSupportedException - Search operation not supported with xConnect collection-only configuration Are you also getting this error “ NotSupportedException - Search operation not supported with xConnect collection-only configuration ”? So, let me explain to you this issue is related to CD Sitecore instance. The issue is that Sitecore CD servers are set to only use xConnect as a collection-only endpoint. To resolve this issue, open this config “ App_Config\Sitecore\XConnect.Client.Configuration\Sitecore.XConnect.Client.config ” and add “ ContentDelivery ” role in role:require attribute just like below code. <clientconfig type="Sitecore.XConnect.Client.Configuration.SitecoreXConnectClientConfiguration,Sitecore.XConnect.Client.Configuration" singleInstance="true" role:require="ContentDelivery or Standalone or ContentManagement"> <param desc="clientModel" ref="xconnect/runtime" />
