I'm consuming an api that uses an empty string for a null but sends an object when the key is not null like so:
```
"mods":{"mod1":""}
"mods":{"mod1":{"comp":"&gt;=","point":3}}
```
Is there a way to construct a class or annotate the property to deal with this?

I was battling with this yesterday. Basically inferring type from the payload is not possible.

You definitely need a custom serialiser though. Have a look at <https://github.com/Kotlin/kotlinx.serialization/blob/a45e71af8bff3f76a3774fd0f8a1425de800a847/runtime/commonMain/src/kotlinx/serialization/json/JsonElementSerializer.kt> .

That’s the route I ended up going down. It wasn’t too painful.  I made the custom serializer on the object containing the switchable key and returned a default empty mod1 object if the value was a json literal type.
