Hey, the KotlinxSerializer is apparently unable to deserialized JSON payloads having lists at the root. For instance, a JSON payload like the following:

[{"foo": "bar1"}, {"foo": "bar2}]

would not be deserialized correctly.

After some trial and error, the problem lies on KotlinSerializer.kt:94:

    private fun lookupSerializerByType(type: KClass<*>): KSerializer<*> {
        mappers[type]?.let { return it } // <--
        return (type.defaultSerializer() ?: type.serializer())
    }

From what I understand, no mapper will be found because type would be kotlin.collections.List. Is that correct?

Thank you in advance 😃

Parsing lists is already working in ktor version 1.3.0 (currently beta). In this new version there is no need to register the serializers.
