Can't get a list of archived tickets via archivedTickets API endpoint

Can't get a list of archived tickets via archivedTickets API endpoint

Hi.

Each time I try to get a list of archived tickets I receive a 204 error (no data).  I am using https://desk.zoho.eu/api/v1/tickets/archivedTickets?limit=50&departmentId= as my endpoint (valid department ID is appended after the equals sign).  Am I doing something wrong here?  All other APIs working fine. 

FYI, I am using Postman to test.

Thanks,

Carl.
