string indices must be integers

C1234

Hey whenever I place my orders, the orders usually get executed, however sometimes, I get the error:
"string indices must be integers"

Here is a gist of my code:

client_smartApi=SmartConnect(api_key='api_key')
login = client_smartApi.generateSession('Client_id','password')
try:
orderparams = {
"variety": "NORMAL",
"tradingsymbol": tradingsymbol,
"symboltoken": symbol_token,
"transactiontype": transactiontype,
"exchange": symbolexchange,
"ordertype": "MARKET",
"producttype": "CARRYFORWARD",
"duration": "DAY",
"quantity": quantity
}
orderId=client_smartApi.placeOrder(orderparams)
except Exception as e:
print(e)

Hello Guys,

the solution is to reset token, as below.

try:
data = self.obj.generateSession(client_id,Password)
return data['data']['refreshToken']
except Exception as e:
print ("Login failed: {}".format(e))
