BitMart 'X-BM-SIGN' Error 30005

Dear Kroitor,

Please could you advise on this error?

I get request authentication signing errors for BitMart with two sets recently created API keys only, on two new accounts. The same application (same code) has been running successfully on BitMart with over 10 other sets of API keys for many months.

Account balances are fetched successfully, which suggests that the keys are valid, but trade operations such as cancellation throw a SIGN error (30005), below.

There are some ideas proposed on the BitMart API repo.

Environment

• OS: Both Mac OS 10.15.4 & Windows Server 2019 Datacentre
• Programming Language version: Python 3.9
• CCXT version: 1.76.65 (latest)

Set-up

        self.ccxt = self.exchange_class({
            'apiKey': config['apiKey'],
            'secret': config['secret'],
            'uid': config['uid'],
            'options': {
                'defaultType': os.getenv('INSTRUMENT'),
            },
            'enableRateLimit': True,
        })
        self.ccxt.load_markets()

Example Code

    try:
        result = self.ccxt.cancel_order(order.exchange_id, order.symbol)
    except Exception as e:
        logger.warning(f'id {order.exchange_id} cancellation FAILED... ({e})')
        assess_connection(exchange, e)

Output Error

id 2482643 cancellation FAILED...  (bitmart {"message":"Header X-BM-SIGN is wrong","code":30005,"trace":"ac973398-xxxx-yyyy-ab1b-578da2e583c6","data":{}})

I made them show me a screenshot of the key and turns out they were not supplying the correct data for uid (BitMart memo). This has been a waste of our time and yours, I apologise, we had given clear instructions regarding the API key. Assume it is the same for the second key. Thanks for your time. PS do you have a sales guy we can speak to about CCXT Pro, interested to explore if/how it could be useful.
