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?
