Error: __on_close_callback() takes from 1 to 2 positional arguments but 4 were give

[alokgpee]

Getting below issue very frequently after some time of running program.

ERROR:websocket:error from callback <bound method AlphaTrade.__on_close_callback of <alphatrade.alphatrade.AlphaTrade object at
0x0000025FC445FF70>>: __on_close_callback() takes from 1 to 2 positional arguments but 4 were given

Generally happens on calling following function:
sas.subscribe(optionType, LiveFeedType.COMPACT)

Trace logs are as follows:

Is it possible for your to share the code? using code formatting. I will check it out

Hi @algo2t, I am also receiving this error quite often. It happens sporadically.

2022-08-23 12:52:01,310 - ERROR - algo_test.py:292 - Error in subscribing to main instrument : EOF occurred in violation of protocol (_ssl.c:2384)

This happens when I try to subscribe to Nifty feed. Probably it could be for any instrument and not just for Nifty.

try:
    x = sas.get_instrument_by_symbol('NSE', 'Nifty 50')
    sas.subscribe(x, LiveFeedType.COMPACT)
    subscribed = len(sas._AlphaTrade__subscribers)
    sleep(1)
except Exception as e:
    logging.error('Error in subscribing to main instrument : ' + str(e))

Does it has something to do with insufficient memory (RAM)? or anything else? Kindly help.
