Error while reading data from csv file using pandas

import yfinance as yahooFinance
import time
import datetime
import pandas as pd

ticker = 'TSLA'

period1 = int(time.mktime(datetime.datetime(2022, 12, 1, 23, 59).timetuple()))  # year,month,date
period2 = int(time.mktime(datetime.datetime(2022, 12, 31, 23, 59).timetuple()))  # year,month,date
interval = '1wk'  # time interval
query_string = f'https://query1.finance.yahoo.com/v7/finance/download/{ticker}?period1={period1}&period2={period2}&interval={interval}&events=history&includeAdjustedClose=true'
df = pd.read_csv(f'https://query1.finance.yahoo.com/v7/finance/download/{ticker}?period1={period1}&period2={period2}&interval={interval}&events=history&includeAdjustedClose=true')
print(df)

The above is my code when I run it , the following error comes

Both period1 and period2 are invalid, as they lie in the future. Adjust them e. g. with datetime.date(2021,4,5) or datetime.date.today() to get the current date, which is the latest possible date.

import time
import datetime
import pandas as pd

ticker = 'TSLA'

period1 = int(time.mktime(datetime.date(2021,4,5).timetuple()))
period2 = int(time.mktime(datetime.date.today().timetuple())) 
interval = '1wk'

query_string = f'https://query1.finance.yahoo.com/v7/finance/download/{ticker}?period1={period1}&period2={period2}&interval={interval}&events=history&includeAdjustedClose=true'

df = pd.read_csv(query_string)
