What platform are you running this code on?

[Jeremy]

Common module

[ribesg]

That’s not a platform

[Jeremy]

Android+iOS

[ribesg]

Use setMapper instead of register

[Jeremy]

Hmm I tried that also same issue

[ribesg]

Oh, it’s a list. Top level lists aren’t supported because “they’re not proper json” or something like that

[ribesg]

The workaround is a custom deserializer

[ribesg]

Like ContentsResponseList(val list: ContentsResponse) and then you use this type as return type and have a custom deserializer which returns the list inside directly

[Jeremy]

🤔 This works ok: Json.nonstrict.parse(ContentsResponse.serializer.list, stringResponse)

[ribesg]

[ribesg]

And then you use get<Foobars>(...).list

[ribesg]

It’s not a problem with the deserialization, it’s a problem with finding the deserializer

[Jeremy]

Great thanks. I'll try that out and let you know

[Jeremy]

Will this method perform differently than retrieving and parsing the string?

[Jeremy]

KN serialization doesn't support io streams yet right?

val httpClient = HttpClient {
install(JsonFeature) {
serializer = KotlinxSerializer(Json.nonstrict).apply {
setMapper(ContentResponseList::class, ContentResponseList.Companion)
}
}
}

internal class ContentResponseList(val list: List<ContentsResponse>) {

@Serializer(ContentsResponse::class)
companion object : KSerializer<ContentResponseList> {
override fun serialize(encoder: Encoder, obj: ContentResponseList) =
ContentsResponse.serializer().list.serialize(encoder, obj.list)

override val descriptor =
StringDescriptor.withName(ContentResponseList::class.simpleName!!)
}
}

[jeremy]

Same error
