PYTHON: not getting ticks with kite3.0 KiteTicker

MAG

I am migrating my code over to kiteconnect 3.0 and I am stuck with the websocket library receiving ticks.
The following is excerpt from working code for kiteconnect 2.0 that was modified for kiteconnect 3.0 as per the documentation.

Can you please help me find out whats wrong? The connection seems to instantiate fine. But Its not getting any ticks
When I run the code, it calls the on_connect method successfully but then nothing seems to happen. No ticks. Just to confirm I added a bunch of instrument tokens and not just one. The logic is between these instrument tokens there would definitely be one tick generated per second.

    print("Onconnect called")

Seems like your `on_tick` callback is wrong. It takes `ws` WebSocket object as first param and `ticks` as second param. Check example for reference - https://github.com/zerodhatech/pykiteconnect#websocket-usage

Ignore this for the moment. I think I have got this sorted.

This has been resolved. Minor issues and RTFM multiple times helped solved the issue.
It was
kws.on_ticks = on_ticks # in kiteconnect 3.0
instead of
kws.on_tick = on_tick # in kiteconnect2.0

@vivek What does this error mean
on_close(): ERROR : 1006, connection was closed uncleanly (I dropped the WebSocket TCP connection: not enough arguments for format string)

Vivek

Seems like you are trying to format a string in your callback without any argument. So basically if your logic is wrong in callbacks it will be raised like this.
