This is runtime error. Looks like datetime parsing is failing. But i have passed proper date_format. What could be the issue ?

Hi,
That is an error in the parsing of the url response as csv. Usually this error means the document coming back from your url is not actually csv, but some kind of html wrapper/display for the csv.
thanks,
fawce
