No matter how much I change my code or parameters, I am gain and again getting an empty dataset

AJ2610

I am very new to coding and Zerodha API, I subscribed to it in the evening.
First of all, Iearnt from the internet that I could fetch the historical data for as long as I wanted, but when I tried to fetch 2yr long data for 15 minute candle. My IDE showed an error that it can't exceed 200 days.

Second, I don't know why how much I am changing my code, the symbol, the dates or the interval. My code is returning everytime an empty dataset. Following is a slice of my coding logic and the output.
Please explain.

CODE
.........
def fetch_historical_data(symbol, interval='day', from_date='2023-11-01 09:15:00', to_date='2023-11-18 15:30:00'):
url = f"https://api.kite.trade/instruments/historical/{symbol}/{interval}"
params = {
'from': from_date,
'to': to_date
}
headers = {
'X-Kite-Version': '3',
'Authorization': f'token {api_key}:{access_token}'
}

response = requests.get(url, params=params, headers=headers)

if response.status_code == 200:
return response.json()['data']
else:
print(f"Failed to fetch data for symbol {symbol}. Status code: {response.status_code}, Response: {response.text}")
return None

symbol = '605697'
historical_data = fetch_historical_data(symbol)

if historical_data:
df = pd.DataFrame(historical_data, columns=['timestamp', 'open', 'high', 'low', 'close', 'volume'])

df['timestamp'] = pd.to_datetime(df['timestamp'])

df.set_index('timestamp', inplace=True)

# Print the DataFrame
print(df)


OUTPUT

Empty DataFrame
Columns: [open, high, low, close, volume]
Index: []

Can you enable debug logs as mentioned here?
And paste the complete stack trace here. Make sure to remove app and client specific tokens.

GOT RESOLVED. THERE WAS SOME ERROR FROM MY SIDE IN CODING. SORRY.
THANK YOU FOR YOUR RESPONSE @sujith

And can you please guide me about how old the data can be extracted for different timeframes?
