getCandleData() missing 1 required positional argument: 'historicDataParams'

[Boofy]

I have been trying to use the historical data but I am encountering this issue every time.
Please tell me what mistake I am making below:

import smartapi

hist = {
    "exchange": "NSE",
    "symboltoken": "3045",
    "interval": "ONE_MINUTE",
    "fromdate": "2021-02-08 09:00", 
    "todate": "2021-02-08 09:16"
}

try:
    smartapi.SmartConnect.getCandleData(hist)
except Exception as e:
    print("Historical API failed: {}".format(e))

And this is the error I am encountering:

Historical API failed: getCandleData() missing 1 required positional argument: 'historicDataParams'

Thank you @pavank
I realized it later.

THE ISSUE IS SOLVED
I needed to use the initiated object of SmartApi class.

import secrets
import smartapi

#create object of call
obj = smartapi.SmartConnect(api_key=secrets.datafeed_key)

#login api call
loginData = obj.generateSession(secrets.client_id,secrets.pswd)
refreshToken= loginData['data']['refreshToken']

#fetch the feedtoken
feedToken = obj.getfeedToken()

#fetch User Profile
userProfile = obj.getProfile(refreshToken)

hist = {
    "exchange": "NSE",
    "symboltoken": "3045",
    "interval": "ONE_MINUTE",
    "fromdate": "2021-02-08 09:00", 
    "todate": "2021-02-08 09:16"
}

try:
    hist_data = obj.getCandleData(hist)
    print(hist_data)
except Exception as e:
    print("Historical API failed: {}".format(e))

This is the code in case someone else also encountered something like this.

EDIT:

I also tried this:

try:
    smartapi.SmartConnect.getCandleData(historicDataParams=hist)
except Exception as e:
    print("Historical API failed: {}".format(e))

But after doing that I get this error:

[Boofy]

@pavank Are you using same snippet from GitHub?
If not can you share yours?

Hello @pavank,
I tried logging in and then executing the same code but still the result is same.

See here below:

But when I do this:

try:
    smartapi.SmartConnect.getCandleData(hist, hist)
except Exception as e:
    print("Historical API failed: {}".format(e))

Somehow previous error gets resolved, though that should not happen.
But after doing this I get new kind of error:

@Boofy you need to login before requesting historical data.
