Data missing for Historical Fetches using Upstox API

I was fetching the historical data for some indexes yesterday and I found that the data for the entire 2019 year is not being fetched and also for 2021 partially (Jan to August). See examples below . Can someone please fix this asap. Its holding me back from using the data and doing the further calculations that I need.

The data does appear from August 2021 but it doesn’t for some other months and days too. I have a limit of posting just 2 links since I just joined the community so can’t post more links below. But please can someone take a look at this urgently.

Why is this still not fixed ? After 31st Dec 2020 Data for Daily Timeframe I’m directly getting 9th August 2021. What the hell is this. Also 2019 data is still missing. Is there any sense of urgency ?

Why the hell am I facing an issue now with JSL too, no data for 3rd Nov 2025 - This is pathetic.
