ErrorException
Warning: count(): Parameter must be an array or an object that implements Countable

/app/vendor/ccxt/ccxt/php/binance.php in ccxt\binance::fetch_markets at line 725

 $markets = $this->safe_value($response, 'symbols');
$result = array();
for ($i = 0; $i < count($markets); $i++) { <= The ErrorException occurred here.
      $market = $markets[$i];

It seems that Binance did not send a correct response and therefore this loop failed. I think it would be good if there would be a check on $markets so a more clear Exception could be thrown, or retry? Or whatever is more suitable.

I had a few of these errors in my Sentry logs, so it’s not a big deal, but I think it would be good, if it will be fixed.

sorry for the delay in reply, apparently it is fixed in the latest version CCXT v1.41.81
