Hello, support team.
I'm use EIKON api. this command is error.
-------------------------------
import eikon as ek
ek.set_app_id('*************************')
df, err = ek.get_data(['1313.T'], fields=['TR.EventType']) --> Backend error 400
df, err = ek.get_data(['1313.T'], fields=['TR.EventType.date']) --> Backend error 400
df, err = ek.get_data(['1313.T'], fields=['TR.TickerSymbolCode']) --> no problem.
-------------------------------
It worked fine until Sep 17th.
Please research this issue.
Best regards,
