Error with exchange_info()

[rabolon]

My error:

src/binance_mod.rs:217 2025-11-21T02:29:44 [INFO] - Error kind: ReqError(reqwest::Error { kind: Decode, source: Error("unknown variant MAX_NUM_ORDER_LISTS, expected one of PRICE_FILTER, PERCENT_PRICE, PERCENT_PRICE_BY_SIDE, LOT_SIZE, MIN_NOTIONAL, NOTIONAL, ICEBERG_PARTS, MAX_NUM_ORDERS, MAX_NUM_ALGO_ORDERS, MAX_NUM_ICEBERG_ORDERS, MAX_POSITION, MARKET_LOT_SIZE, TRAILING_DELTA", line: 1, column: 1867) })

My code:

pub fn exchange_info(api_url: &str) -> Option<ExchangeInformation> { let config = Config::default().set_rest_api_endpoint(api_url); let general: General = Binance::new_with_config(None, None, &config);

match general.exchange_info() {
    Ok(answer) => {
        log::info!("{:?}", answer);
        Some(answer)
    },
    Err(e) => {
        log::info!("Error kind: {:?}", e.kind());
        None
    }
}

}
