BinanceAPIException: APIError(code=-1100): Illegal characters found in parameter 'symbol'

[ufotje]

Describe the bug A clear and concise description of what the bug is. I saw this error for many of the other parameters too. I'm trying to get historical_klines Before I used a hardcode value and it worked fine, now I get the symbol from a querystring, which results in this error

To Reproduce @app.route('/history') def history(): symbol = request.args.get('symbol') candlesticks = client.get_historical_klines(symbol=symbol, interval=Client.KLINE_INTERVAL_5MINUTE, start_str="10 Jan, 2021")

Expected behavior To get the klines from jan 10th till know with 5min candlesticks

Environment (please complete the following information):

• Python version: 3.8.5
• Virtual Env: [e.g. virtualenv, conda]venv
• OS:Windows
• python-binance version

Dear ufotje,

There is no actual value of the symbol in the provided logs. Please use logger, print, PDB, or any other approach to figure out the actual value of the symbol you're receiving in symbol = request.args.get('symbol').

[ufotje]

This is the method I use to ge the historical klines: @app.route('/history') def history(): symbol = str(request.args.get('pair')) if request.args: candlesticks = client.get_historical_klines(symbol=symbol, interval=Client.KLINE_INTERVAL_30MINUTE, start_str="10 Jan, 2021") else: candlesticks = client.get_historical_klines(symbol="btceur", interval=Client.KLINE_INTERVAL_30MINUTE, start_str="10 Jan, 2021")

    processed_candlesticks = []

    for data in candlesticks:
        candlestick = {
            "time": data[0] / 1000,
            "open": data[1],
            "high": data[2],
            "low": data[3],
            "close": data[4],
    }
    processed_candlesticks.append(candlestick)

    return jsonify(processed_candlesticks)

This is where it's being called: fetch('http://localhost:5000/history') .then((r) => r.json()) .then((response) => { console.log(response) candleSeries.setData(response); }) I subscribe to a webstream later in the code using the same variable and that works, so I know that the variable is being set in the html var binanceSocket = new WebSocket("wss://stream.binance.com:9443/ws/" + pair +"@kline_5m");

Oh, I think I know what is the problem here. Please do next

client.get_historical_klines(symbol=symbol.uppper(), interval=Client.KLINE_INTERVAL_30MINUTE,
start_str="10 Jan, 2021")

If you're using a non-uppercase symbol definition, you're receiving this error.

As we say in Belgium: "Toppie!". Silly mistake, but that fixed it, weird that you need an uppercase symbol for the historcal trades, but can subscribe to a stream with a lowercase. Anyways thanks for the assistance
