Unable to get sensex expiaries

I’m trying to get expiries for SENSEX but its not returning any data its returning below response:
{"meta":{"code":"PM_FNO_200","message":"Success","displayMessage":"Success"}}

But in place of other instrument like NIFTY50 it returns valid data.

@sanjoy.dasgupta thanks for writing to us, BSE FO is currently unavailable, we are working to make it live soon.
