Python-binance: client.get_historical_klines returns Illegal characters found in parameter 'endTime'; legal range is '^[0-9]{1,20}$'

[goodyjoon]

klines = client.get_historical_klines(sym, Client.KLINE_INTERVAL_1HOUR, '10 hour ago UTC', 'now UTC')

raises:
BinanceAPIException: APIError(code=-1100): Illegal characters found in parameter 'endTime'; legal range is '^[0-9]{1,20}$'.

And the error is the same no matter how I change start_time and end_time strings.

Yeah, I got the same error this morning. The reason I believe is because python-binance is sending endTime as None in Client.get_klines(), so binance thinks endTime parameter exists on the request and validates the None values against its regex. I believe this pull request addresses this, it strips the None from the parameters so that it doesn't trigger validation from binance's api server.

If somebody got here looking for a fix:

I encountered the same issue today. I downgraded from 0.7.3 to 0.7.2 and it fixed it.

i downgrade from 0.7.3 to 0.7.2 but it is not working yet...

downgrade python-binance from 0.7.3 to 0.7.2 and restart your kernel. it worked for me.

It is possible fix it:
In the file: client.py, on line 733, change:
kline = self.get_klines(
symbol=symbol,
interval=interval,
limit=1,
startTime=0,
endTime=None
)
to:
kline = self.get_klines(
symbol=symbol,
interval=interval,
limit=1,
startTime=0
)

Obs: Remove the "endTime" property

This worked for me.

In my case im interested in getting Kline data with endTime now, so here's a fix:

def _get_earliest_valid_timestamp(self, symbol, interval):
        """Get earliest valid open timestamp from Binance

        :param symbol: Name of symbol pair e.g BNBBTC
        :type symbol: str
        :param interval: Binance Kline interval
        :type interval: str

        :return: first valid timestamp

        """
        kline = self.get_klines(
            symbol=symbol,
            interval=interval,
            limit=1,
            startTime=0,
            endTime=int(round(time.time() * 1000)) <---------------------------------------

        )    
        return kline[0][0]
