Rename the client service class/file from [Module]Service to Client[Module]Service and the server service to Server[Module]Service. Update Edit.razor and Index.razor to inject Client[Module]Service and adjust all calls accordingly. Update DI registration in ClientStartup to register Client[Module]Service. Also remove the System.Net.Http.Json package reference from the client .csproj. File renames and reference updates keep class names and registrations consistent between client and server templates.
