I am attempting to load a group with the following code:
String groupId = ""; // Fill in a group ID here
GroupsApi groupsApi = new GroupsApi();
Group group = groupsApi.getGroup(groupId, false);
This crashes with the following exception:
Error: Expected the field `roleIdsToView` to be an array in the JSON string but got `null`
java.lang.IllegalArgumentException: Expected the field `roleIdsToView` to be an array in the JSON string but got `null`

Looking into this, it does appear that that field is marked as nullable in the specification: https://github.com/vrchatapi/specification/blob/main/openapi/components/schemas/GroupGallery.yaml#L21
and the raw response from the server looks like this:
{
"roleIdsToView": null,
}Inspecting the generated code and setting a breakpoint leads me to this generated code snippet:
// ensure the optional json data is an array if present
if (jsonObj.get("roleIdsToView") != null && !jsonObj.get("roleIdsToView").isJsonArray()) {
throw new IllegalArgumentException(String.format("Expected the field `roleIdsToView` to be an array in the JSON string but got `%s`", jsonObj.get("roleIdsToView").toString()));
}Setting a breakpoint on the throw line reveals that jsonObj.get("roleIdsToView") is not set to null, but to JsonNull:
causing the check for null to fail and the code to crash. I'm assuming this would affect other nullable fields as well; is there a flag or something that needs to be changed with the codegen to fix this?
