after upgraded the smartapi and providing the TOPO details, getting below error while generating the session. data = obj.generateSession(username,pwd,topo) Please provide the solution JSONDecodeError Traceback (most recent call last) C:\ProgramData\Anaconda3\lib\site-packages\smartapi\smartConnect.py in request(self, route, method, parameters) 187 try: --> 188 data = json.loads(r.content.decode("utf8")) 189 C:\ProgramData\Anaconda3\lib\json_init.py in loads(s, cls, object_hook, parse_float, parse_int, parse_constant, object_pairs_hook, **kw) 345 parse_constant is None and object_pairs_hook is None and not kw): --> 346 return _default_decoder.decode(s) 347 if cls is None: C:\ProgramData\Anaconda3\lib\json\decoder.py in decode(self, s, _w) 336 """ --> 337 obj, end = self.raw_decode(s, idx=_w(s, 0).end()) 338 end = _w(s, end).end() C:\ProgramData\Anaconda3\lib\json\decoder.py in raw_decode(self, s, idx) 354 except StopIteration as err: --> 355 raise JSONDecodeError("Expecting value", s, err.value) from None 356 return obj, end JSONDecodeError: Expecting value: line 1 column 1 (char 0) During handling of the above exception, another exception occurred: DataException Traceback (most recent call last) ~\AppData\Local\Temp/ipykernel_4956/2840288024.py in <module> ----> 1 data = obj.generateSession(username,pwd,topo) C:\ProgramData\Anaconda3\lib\site-packages\smartapi\smartConnect.py in generateSession(self, clientCode, password, totp) 226 227 params={"clientcode":clientCode,"password":password,"totp":totp} --> 228 loginResultObject=self._postRequest("api.login",params) 229 230 if loginResultObject['status']==True: C:\ProgramData\Anaconda3\lib\site-packages\smartapi\smartConnect.py in _postRequest(self, route, params) 218 def _postRequest(self, route, params=None): 219 """Alias for sending a POST request.""" --> 220 return self._request(route, "POST", params) 221 def _getRequest(self, route, params=None): 222 """Alias for sending a GET request."""

Got solution as below.
Install pyopt library : pip install pyotp
import pyotp
use the topo detail with pyotp as below:
topo = Trading_api_key_details.topo
topt = pyotp.TOTP(topo)
topt = topt.now()
data = obj.generateSession(username,pwd,topt)
refreshToken= data['data']['refreshToken']
print(data)
