Question about optional fields. Although I marked a field to be String?, kotlin-serialization (client js) expects the fields to be in the json, even when null?
Here’s the error:

MissingFieldException
message_8yp7un$_0: "Field 'firstName' is required, but it was missing"
name: "MissingFieldException"

The json response was:```{id: 8}````
