SDK swallows enum variant when fetching object with SuiClient::get_object_with_options

[porkbrain]

• Use SDK and CLI from tag "testnet-1.33.0"
• Start a local network
• Have the following object in your Move package:

    public struct Foo has key {
        id: UID,
        inner: VecMap<String, Bar>,
    }

    public enum Bar has store {
        A(ID),
        B(ID),
    }

• Fetch that Move object with Sui SDK

let object_resp = sui.read_api()
            .get_object_with_options(
                your_object_id,
                SuiObjectDataOptions {
                    show_content: true,
                    ..Default::default()
                },
            )
            .await
            .unwrap();

let json = object_resp.data
            .unwrap_or_else(|| panic!("No data found for Foo at {your_object_id}"))
            .content
            .unwrap_or_else(|| panic!("No content found for Foo at {your_object_id}"))
            .try_into_move()
            .map(|SuiParsedMoveObject { fields, .. }| dbg!(fields).to_json_value())
            .unwrap_or_else(|| panic!("Foo at {your_object_id} is not a Move object"));

I would expect to see which variant of Bar was used. When I open my local explorer provided by Suibase, I can actually see the variant there.

The SDK swallows the variant parameter. While I can see "pos0" representing Bar::A or Bar::B positional argument, the actual variant is not present. I get something like:

{
  "key": String("text"),
  "value": Struct(WithTypes {
      type_: StructTag { .. },
      fields: { "pos0": Address(0xdef) },
    }),
}

But the explorer correctly shows me:

{ 
  "key": "text",
  "value": {
    "type": "0xabc::foo::Bar"
    "variant": "A",
    "fields": { "pos0": "0xdef" }
}
