rest_api.query_order(), cannot subscript object of type `QueryOrderResponse` with no `__getitem__` method

[archerallstars]

From the recent SDK update, the return of data = response.data() of client.rest_api.query_order is a dictionary.

But when I tried to access the data like status = data["status"], it works at runtime, but it reports an error in my editor:

Cannot subscript object of type `QueryOrderResponse` with no `__getitem__` method

This is likely due to incorrect or incomplete type definitions in the SDK, causing the linter/diagnostics to report errors that don't align with actual runtime behavior.

My workaround in order to suppress the error is casting the data with data = cast(dict, response.data()). It's supposed to work without the casting.

My full example script

import logging
from binance_sdk_derivatives_trading_usds_futures.derivatives_trading_usds_futures import (
  ConfigurationRestAPI,
  DerivativesTradingUsdsFutures,
)

# Configure logging
logging.basicConfig(level=logging.INFO)

# Create configuration for the REST API
configuration_rest_api = ConfigurationRestAPI(
  api_key="xxx",
  api_secret="xxx",
  base_path="https://demo-fapi.binance.com",
)

# Initialize DerivativesTradingUsdsFutures client
client = DerivativesTradingUsdsFutures(config_rest_api=configuration_rest_api)


def query_order():
  try:
      response = client.rest_api.query_order(
          symbol="BTCUSDT",
          order_id=12035280468,
      )
      data = response.data()

      # Extract and print the specific values - treating data as dict based on print output
      status = data["status"]
      print(f"Status: {status}")

  except Exception as e:
      logging.error(f"query_order() error: {e}")

Given response.data() returns a dict at runtime. As a thought, this is a stub/annotation issue, you could try to change the return type of response.data() (or query_order) from QueryOrderResponse to Mapping[str, Any]/dict[str, Any] (or expose a .data: dict[...]), so data['status'] is type-correct without cast().”
