The stacktrace shows a call to lookupSerializerByType which does not look for serializers in listMappers (where registerList<Long>() places the serializer).

Hi @pardom. Unfortunately, deserialization of generic collections isn't supported for now(in common code).

[pardom]

Hmm, I’m using the JVM runtime. Is the lack of support in Ktor or kotlinx.serialization?

[e5l]

Probably kotlinx.serialization side.

okay, thanks.
