Index.updateSettings with filterableAttributesConfig fails with Jackson

[jebbench]

Description
When using the filterableAttributesConfig settings property an exception is thrown.

It looks like Jackson is attempting to serialise the Settings.getFilterableAttributes accessor causing it to throw a "don't use me" exception.

Example Code

val idx = meili.index(INDEX_NAME)
idx.updateSettings(Settings().apply {
    filterableAttributesConfig = arrayOf(
        FilterableAttributesConfig(arrayOf("parent"), FilterableAttributesFeatures().apply {
            filter = FilterableAttributesFilter(true, false)
            facetSearch = false
        }),
        FilterableAttributesConfig(arrayOf("other", "third"), FilterableAttributesFeatures().apply {
            filter = FilterableAttributesFilter(true, true)
            facetSearch = false
        })
    )
})
