Hi, I’m seeing an error when i run :

mutation attempt of frozen kotlin.collections.HashMap@2be0d88

I’ve tried the fix here : https://github.com/Kotlin/kotlinx.serialization/issues/1450 but it still fails

just to confirm, you tried setting useAlternativeNames to false?

that's at least what fixed that for me here on 2 different projects
