Unable to parse nested relationships

[jutikornpomelo]

My JSON response has 3 nested relationships in it which looks like this:

lib can parse the blue and red layers but when it comes to the green layer. It cant be parsed and only return null

My data class:

@JsonApi(type = "navigation-items")
data class JsonNavigationItem(
    @field:Json(name = "id_category") val categoryId: Int? = null,
    val name: String? = null,
    @field:Json(name = "text_color") val textColor: String? = null,
    val media: JsonMedia? = null,
    @field:Json(name = "navigation-items") val navigationItems: HasMany<JsonNavigationItem>? = null,
) : Resource()

Here is my sample json:

    "data": [{
            "type": "navigation-items",
            "id": "3169",

A resource linkage object (the data field in values of relationships field) can be a single or an array of resource identifier object. AFAIK, the use of relationships in a resource identifier object is not supported by the specification.
