xConnect error in 9.1: One or more local models conflict with the xDB service layer

Question

I've added a custom facet and model, serialized the model and deployed it to my xConnect server to the two locations outlined in Sitecore's documentation but I'm still seeing this error. Because of the error the site cannot start the tracker so I'm unable to record any interactions about users.

I'm running 9.1 locally using the Standalone role.

Model

public class AgentInfoModel
{
    public static XdbModel Model { get; } = AgentInfoModel.BuildModel();

    private static XdbModel BuildModel()
    {
        XdbModelBuilder modelBuilder = new XdbModelBuilder("AgentInfoModel", new XdbModelVersion(1, 0));

        modelBuilder.DefineFacet<Contact, ContactAgentInfo>(ContactAgentInfo.DefaultFacetKey);
        modelBuilder.ReferenceModel(Sitecore.XConnect.Collection.Model.CollectionModel.Model);

        return modelBuilder.BuildModel();
    }
}

JSON:

"Name": "ContactAgentInfo",
"Version": "1.0",
"References": [
{
  "Name": "XConnect",
  "Version": "1.0"
}

Error:

Exception: Sitecore.XConnect.Client.XdbModelConflictException Message: One or more local models conflict with the xDB service layer. 'AgentInfoModel, 1.0' does not have a remote version

Answer 1

Your model builder is making a model named "AgentInfoModel". But the JSON you posted is for a model called "ContactAgentInfo". The Name field of you JSON should match the name and version you specified on the XdbModelBuilder class.

I believe you may have renamed your model at some point and forgot to regenerated your json model.

This

XdbModelBuilder("AgentInfoModel", new XdbModelVersion(1, 0))

Does not match this:

{
   "Name": "ContactAgentInfo",
   "Version": "1.0",
   "References": [
   {
      "Name": "XConnect",
      "Version": "1.0"
   }
}

One last thing, you mentioned logging user interactions. When you want to use your facet for interactions, you need to define your facet as an Interaction facet in the builder. Your facet is currently defined as a Contact facet.

modelBuilder.ReferenceModel(Sitecore.XConnect.Collection.Model.CollectionModel.Model);

modelBuilder.DefineFacet<Interaction, ContactAgentInfo>(ContactAgentInfo.DefaultFacetKey);```
