get_option_analytics InstrumentTag = None

If I run the following code :

import refinitiv.dataplatform as rdp
import datetime
import asyncio

rdp.open_desktop_session('key')


test = rdp.ipa.FinancialContracts.get_option_analytics(universe = ["ADBEL232168000.U", "ADBEL232169000.U"])
print(test.data.df)

The InstrumentTag you would expect to return the inputted rics: e.g.

"ADBEL232168000.U" and  "ADBEL232169000.U"

however it returns None, how is this possible?
