Set of Tasks/Futures is empty.

[nirnaeth-arnoediad]

Trying to connect my mg4 through mgtt gateway but getting an error shown below.
Using ubuntu 24.04 (vm) to setup bridge.
App/Car Location is Turkey (tried different regions but app wont allow me to login/bind the vehicle via QR).
Using EU app (turkish version's account is not even recognized).
I suspect that vehicle list is empty so container crashes.

Here the logs:

I'm using gateway-mg-au.soimt.com for Australia, and I get the same error when I use a secondary account.

I tried upgrading from 0.4.6 because it stopped working. I used this for a long time as the only version that worked for Australia. Version 0.4.6 gives me a different error: saic_ismart_client.exceptions.SaicApiException: return code: 502, message: Service side connection has exception.

The user above is correct about the vehicle list being empty. I added an info print to confirm:

saic-mqtt-gateway  | 2025-11-30 03:47:05,919 [INFO]: Fetching vehicle list - mqtt_gateway
saic-mqtt-gateway  | 2025-11-30 03:47:05,949 [INFO]: VIN list: VehicleListResp(vinList=[]) - mqtt_gateway

Attempting to get vehicle_list() using saic_ismart_client_ng, I get the same empty response. To me, this indicates that if there is any problem, it liest in the upstream dependency, not in saic-python-mqtt-gateway.

To test this, I used the main account to authenticate and I did get a vehicle list. I suspect the secondary account is missing permission for the vehicle(s).

@nirnaeth-arnoediad, can you confirm whether you're testing using the main account or a secondary account?

[nirnaeth-arnoediad]

@thiagofigueiro thanks for your response. Here my workflow:

First I install ismart app for turkey and created an account there and bind the car.

I tried the gateway with it but it does not even log in to my account so I switched my phone location downloaded i smart app for eu (specificly mg i-smart uk app) then created a new account cuz my previous i smart account does not recognized obviously different databases. Unbinded the car from turkey app rebind it from eu app than tried the gateway it login to account but returns vehicle list zero.

On whole process I can freely control the car via i smart app everything is working.

To successfully bind the car to the app I need to select Turkey location no matter what so I suspect my problem is geological.
