Unable to fetch data using Python SDK

[kpsidd]

I am trying to fetch market data using the Python SDK. The reference documentation I am following is from here:
https://github.com/angelbroking-github/smartapi-python

The code is copy pasted from here without the order bit. On running the code, the on_close event gets triggered with the following code and reason:
Code = 1006
Reason = "connection was closed uncleanly (I dropped the WebSocket TCP connection: global name 'JSON' is not defined)"

Is it a missing library that I need to install or some code issue? Can someone advise pls?

@admin Would you mind helping me sir as I've cross checked the feed token again and tried your another code to fetch data but it still the same

[mrchharus]

@admin I've been using this feed token from the starting

[admin]

@mrchharus you're passing wrong feedToken. Please review.

@rjbanna Sorry, missed your reply.

I have the latest SDK. I will try out with your code and see it.

Will update.

@kpsidd Do you have the latest python SDK? I'm using the following code for the socket streaming.

import time, json
from smartapi import SmartConnect, WebSocket

obj = SmartConnect(api_key="KEY")
data = obj.generateSession("USER_ID","PASS")

CLIENT_ID = 'ID'
FEED_TOKEN = obj.getfeedToken()
token = 'nse_cm|2885'

ss = WebSocket(FEED_TOKEN, CLIENT_ID)

def on_tick(ws, ticks):
	print(ticks)

def on_connect(ws, response):
	print("on connect")
	ws.send_request(token)

def on_close(ws, code, reason):
	print("on close")
	ws.stop()


ss.on_ticks = on_tick
ss.on_connect = on_connect
ss.on_close = on_close

ss.connect()
