I tried with ek.get_timeseries('aITWOGDPR',start_date='2020-12-31',end_date='2020-12-31',interval='yearly') and it worked for a while but then I tried again and I got this message 'EikonError: Error code -1 | aITWOGDPR: TimeSeries request failed |'.
What does this error mean? Do I have just to wait Reuters fix the problem?
I tested the code for more than 20 times.
The code only works for 2-3 times.
So I think there is a problem with the backend.
I reported this issue on your behalf to Refinitiv Helpdesk.
