The above exception was the direct cause of the following exception:

Kindly try to redownload the contract master

3

I download the master contract every day at 9:01 AM but still got this error. Why did this error occur for me?

4

every day the contract master needs to be downloaded after 8 am Before 08:00 AM the previous day’s contract file is downloaded which is a known condition, as it is done technically, due to any glitch or any network issue .etc, the contract master wouldn’t be downloaded properly, as you set time to download the contract master try to make sure the file is downloaded as expected or not, if not then try to download manually once again.

5

How will we know that master contract data is downloaded correctly or not? And what was the glitch today?

6

Any update Aliceteam

@nandagopal Please update here.

The sign when the contract master is not downloaded properly, if the get_instrument_by_symbol or token gives error message like not found the exchange or the symbol.
