Historical data older than Jan 1 2008

Using below api I can fetch data of Infosys stock from 2008 Jan 1 to till date.

curl --location ‘https://api.upstox.com/v3/historical-candle/BSE_EQ|INE009A01021/days/1/2008-01-01/2001-01-01’

However, no data exists from Jan 1 2000 to Jan 1 2008.

As per documentation at Historical Candle Data V3 | Upstox Developer API unit as days with interval 1 should have data from Jan 1 2000.

I have tried calling the api with and without Authorization/access token but getting no data prior to Jan 1 2008.
