+Enumerations (enum) are transmitted as strings.  If you use an enum in any of your models, you will additionally have to add `typeof(JsonStringEnumConverter<TEnum>)` to the list of converters, where `TEnum` is the type of the enum you are using.  Repeat this for each enum you are using.  For example, let's say you have multiple models.  One of your models is using the enum `CategoryType` and another model is using `CustomerType`, your Converters section would look like this:
+
+    Converters = [
+      typeof(JsonStringEnumConverter<CategoryType>)
+      typeof(JsonStringEnumConverter<CustomerType>)
+      typeof(DateTimeConverter),
+      typeof(DateTimeOffsetConverter),
+      typeof(TimeOnlyConverter),
+      typeof(SpatialGeoJsonConverter)
+    ]

 Add a `JsonSerializable` attribute for each entity that is stored in your `DbContext` similar to the ones in the example above.  Finally, install the modified `JsonSerializerContext` in the `MauiProgram.cs` as the second statment in the `CreateMauiApp` function:
 
     DatasyncSerializer.JsonSerializerOptions.TypeInfoResolver = MySerializerContext.Default;
