streaming message line handling

[tomw777]

Hi, i don't know if it's here i can ask this question (all new to python & co.).

could this problem be due to a misshandling of the threading ? if yes, how could i correct this in order to treat each incoming line ?

Thanks

Issue subject

when streaming the data, using the streaming script, i'm subscribing to streams. ws_client.live_subscribe(stream=["btcusdt@kline_1m"], id=1, callback=message_handler) def message_handler(message): print(message) line_export = message.get('k') int_opentime = int(line_export.get('o')) print(int_opentime)`

i tried this in the message_handler function :

message.get('k').get('o')

in order to extract the open time

Expected behaviour

i thought i should be able to extract data and treat them from the streaming functions

Actual behaviour

error messages : Unhandled Error
