The problem occurs when you try to expand nested objects. For example if you run the project and execute the following OData query:
You will get error below. Most important part of the error is: "Cannot compare 'member 'Participants' of type 'ODataWebApplication.Entities.Dto.InteractionDto''. Only primitive types, enumeration types and entity types are supported.""
