Is there any way to treat

null

in JSON as absent? I have a

val foo: List<String> = emptyList()

which fails to be parsed if

foo

null

in the JSON

Custom encoder.

I thought about that but since I couldn’t find a

peek

or similar on

Decoder

I don’t know how I would check if it’s null

There are two ways around this. Use the new

NullableSerializer<T>

or use

decodeJson

and eagerly parse the json manually.

The first being the preferable option.
