From the error, it is a permission issue. The Eikon's account doesn't have a permission to request time-series data of this RIC (.VINXNOKNI).

You can contact your Thomson Reuters' account team or local support team for the permission (https://my.thomsonreuters.com/ContactUsNew).

Try adjusting the time series start and end dates, the data point we have is for 2012-07-13

Thanks for the tip but unfortunately doesnt work either. With other index (.OSEBX) it does work.

Here is my code:

import eikon as ek
ek.set_app_id('<your app id>')
ek.get_timeseries([".VINXNOKNI"], fields=["TIMESTAMP","Close","VOLUME"], start_date = "2012-12-01", end_date = "2012-12-27",interval="daily")

Here is the result:

.VINXNOKNI   CLOSE  VOLUME
Date
2012-12-03  143.32     NaN
2012-12-04  142.92     NaN
2012-12-05  143.39     NaN
2012-12-06  144.00     NaN
2012-12-07  144.28     NaN
2012-12-10  144.43     NaN
2012-12-11  145.51     NaN
2012-12-12  144.96     NaN
2012-12-13  143.79     NaN
2012-12-14  144.38     NaN
2012-12-17  144.33     NaN
2012-12-18  145.41     NaN
2012-12-19  145.89     NaN
2012-12-20  146.05     NaN
2012-12-21  145.78     NaN
2012-12-27  146.46     NaN

Thanks I tried this but also doesnt work. I am using the R package on github https://github.com/ahmedmohamedali/eikonapir

This might be related to the R package I guess. When I try exact same code with OSEBX it does work.
