Kusama Asset Hub fail to decode Account Info (type ID 1) on early blocks

Description

While trying to decode Account Info (type ID 1) in polkadot-rest-api (code), the below error message is returned:

{
  "error": "Balance query failed: Failed to decode storage value: Failed to decode account info"
}

Chain: Kusama Asset Hub
Block: 10004

Example Request

v1/accounts/1HwQbUpcr99UA6W7WBK86RtMHJTBWRazpxuYfRHyhSCbE1j/balance-info?at=10004

Attempting to Decode with scale_value::Value<()>

Attempting to decode with scale_value::Value<()> also fails.

If replacing this code

    let decoded: Value<()> = value.decode_as().map_err(|_e| {
        BalanceQueryError::DecodeFailed(parity_scale_codec::Error::from(
            "Failed to decode account info",
        ))
    })?;

with this code

    let decoded: Value<()> = match value.decode_as() {
        Ok(v) => v,
        Err(e) => {
            match value.decode_as::<scale_value::Value<()>>() {
                Ok(raw) => {
                    tracing::error!(
                        "decode_account_info: decode_as failed ({e}), but raw Value decoded as: {raw:?}"
                    );
                }
                Err(raw_err) => {
                    tracing::error!(
                        "decode_account_info: both decode_as ({e}) and raw Value decode ({raw_err}) failed — likely missing or incorrect legacy types"
                    );
                }
            }
            return Err(BalanceQueryError::DecodeFailed(
                parity_scale_codec::Error::from("Failed to decode account info"),
            ));
        }
    };

it returns

Start with crates/server/src/handlers/common/accounts/balance_info.rs around the account-info decoding path and reproduce the request for Kusama Asset Hub at block 10004. Trace why type ID 1 produces the reported SCALE decoding error, then verify that the balance-info endpoint decodes this account successfully without a 500 response.
