I want to replicate the following Jupiter Notebook from Refinitiv's Github.

https://github.com/Refinitiv-API-Samples/Article.EikonAPI.Python.SustainablePortfolioSelection/blob/main/SustainablePortfolioSelection.ipynb

But I am stuck at the beginning since I cannot download the MSCI ACWI index constituents.

Line 2 of the the notebook says

"We use Eikon to get the constituents of the index. For simplicity we will reduce the list of entries here to 100."

N=100
constituents, err = ek.get_data(['IWDA.L'], ['TR.ETPConstituentRIC', 'TR.ETPConstituentName'])
constituents.rename(columns={'Constituent RIC': 'ric', 'Constituent Name': 'name'}, inplace=True)
constituents = constituents[['ric','name']][0:N]
print(constituents)

Using the iShares ETF instead of the index seems to be also the solution in this other thread. But I either get a backend error message or either get <NA> .

https://community.developers.refinitiv.com/questions/70410/get-the-historical-constituents-with-rics-and-weig.html

Is there another workaround to get MSCI ACWI constituents?

Thank you
