Unable to download OI Data

Programming NSE Python API

For my code -
oi_data, ltp, crontime = oi_chain_builder("NIFTY")
or
oi_data,ltp,crontime=oi_chain_builder('IPCALAB','latest','full')

I am getting this error:-

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)
<ipython-input-27-7150f307d306> in <module>
      1 print('Data Analysis is commencing.......')
----> 2 oi_data, ltp, crontime = oi_chain_builder("NIFTY")

~\Anaconda3\lib\site-packages\nsepython\rahu.py in oi_chain_builder(symbol, expiry, oi_mode)
    147             oi_data = oi_data.append(oi_row, ignore_index=True)
    148 
--> 149     return oi_data,float(payload['records']['underlyingValue']),payload['records']['timestamp']
    150 
    151 

KeyError: 'underlyingValue'

It was working till Friday. Can you point out where am I going wrong?
Thanks

NSE hired some bad engineers. Sometimes they make certain keywords disappear. Thats what happened yesterday.

Out of 10 days, 1 day, things will break. It is not your problem. You can solve this by joining NSE and becoming their head and then firing those engineers.
