Data Value Sets Fetch API Support for Start and End Date Query Parameters(DHIS2 Language Pack)

Hi Taylor,
You could be right, what is strange though is that if I just pass Period: ‘201705’ or any other month with Period parameter, I get the data. What I am failing to understand is why I can’t get the data whenever I specify the range of dates with startDate and endDate params!

Thanks and kind regards,
Chaiwa.
