I’ve created a scenario in workshop using the new Ontology Scenarios [Beta] following the steps outlined here: https://www.palantir.com/docs/foundry/ontology/overview-ontology-scenario/#scenarios-beta

However I’m trying to load a saved scenario but get this error:

> Some objects do not have valid scenario properties. Ensure all objects either have a property with the “scenarios:versioned-scenario-rid” typeclass or implement the Scenario interface (“com.palantir.core.ontology.scenarios.ontologyScenario”) with a valid “scenarioReference” property. See Workshop scenarios documentation for more info.

As per the instructions it says: “search for the **Ontology Scenario** interface”, however there was no existing Ontology Scenario interface, so I created one. Is this the cause of the error as when I click on ‘Implement new interface’ and search for the required interface: ‘com.palantir.core.ontology.scenarios.ontologyScenario’, it returns no search results
