Hi, I have some problem when I used the follwoing code:
df, err = ek.get_data("SCREEN(U(IN(Equity(active,public,primary))/*UNV:Public*/), IN(TR.RegCountryCode,""US""), TR.TRESGScore(Period=FY0)>0, CURN=USD)",
["TR.CUSIP",'TR.CompanyName',"TR.TRESGScore.Date","TR.TRESGScore","TR.EnvironmentPillarScore",'TR.SocialPillarScore','TR.GovernancePillarScore'],
parameters={'SDate':'0', 'EDate':'-19','Period':'FY0','Frq':'FY'})
It will return a "nontype". It is wired because it works well three month ago.
