FIIDII data is not working

[pradip-interra]

Hello,

While Option OI data for Nifty and BankNifty is working perfectly, not able to make the FIIDII data.

Neither this:

part_oi_df = nd.get_part_oi_df(start=None,end=None,periods=None,dayfirst=False,workers=None)

When I changed it just to fetch today's FII/DII data around 10 PM, I got this error:

part_oi_df = nd.get_part_oi_df(start=today,end=today,periods=1,dayfirst=False,workers=1)
print(part_oi_df)

Error: 
Exception: ('Error occurred while getting part_oi :', 'Of the four parameters: start, end, periods, and freq, exactly three must be specified')

What's the mistake I am doing here?
