GrowthBook v2 Json Arrays Deserialized as "Unknown"

[sbelloz]

Hi!

We noticed that the latest major v2 update of GrowthBook does not properly handle arrays.
When it encounters an array node, it deserializes it as Unknown.
Additionally, I want to ask you how can I obtain a json String or a Map<String, JsonElement> from a GbJson? Maybe having extensions that allow deserialization exclusively on the client side could be useful.

Hello!

No such an option as array for feature value type, but array is used in "in list of values" rule. Seems like you are using this rule

Support for arrays is added in this request (it is not approved yet)

If it is crucial you need to use v1.1.64

For having extensions that allow deserialization exclusively on the client side we should create separate artifact growthbook-kotlinx-serialization as we can't force to use kotlinx-serialization (someone can use Gson)

For fix it right here right now you need to copy this to your project:

fun GBValue.gbSerialize(): JsonElement =
        when(this) {
            is GBBoolean -> JsonPrimitive(this.value)
            is GBString -> JsonPrimitive(this.value)
            is GBNumber -> JsonPrimitive(this.value)
            is GBArray -> JsonArray(
                this.map { it.gbSerialize() }
            )
            is GBJson -> JsonObject(
                this.mapValues { it.value.gbSerialize() }
            )
            is Unknown -> JsonNull
        }
