What error are you getting? Can you read err.message? I believe this is related to binance being down right now

[adityamertia]

Yes looks like this was due to binance being down. However on older versions of the library i was getting null values(i tried in parallel) but in latest version the code failed. Ideally, the library should not crash if binance API/ws are down. This will still count as a bug in my opinion.
