Here is the problematic line: https://github.com/Ricky12Awesome/json-schema-serialization/blob/ea5c0be9a3bc2be152e625dbe17b787a170b603a/src/commonMain/kotlin/com/github/ricky12awesome/jss/internal/JsonSchema.kt#L79

I use a manually created serializer for this class, so it is possible that the descriptor itself is not correct, but the situation is possible.
