ProtoOATraderReq - Trading account is not authorized

Hi I ran into some problems with OpenAPI, when I try to fetch the account data through ProtoOATraderReq, it gives an error saying “Trading account is not authorized”

The code is here, the access setting is set to `Access account and trading`, and I have access token generated in the sandbox. Please help.

Thank you

def get_account_info(self, ctidTraderAccountId):
        request = ProtoOATraderReq()
        request.ctidTraderAccountId = ctidTraderAccountId
        self.client.send(request).addCallback(lambda response: (
            print('Account info:', Protobuf.extract(response)),
        ))

Account info: ctidTraderAccountId: 42879486
errorCode: "INVALID_REQUEST"
description: "Trading account is not authorized"
