I need to embed a map from DHIS2 onto a web page. Dissecting the example @ play.dhis2.org/dem. I get to the map from its API link play.dhis2.org/demo/api/26/maps/ytkZY3ChM6J/data. But when I try the same in the local instance I get;

{"httpStatus":"Internal Server Error","httpStatusCode":500,"status":"ERROR","message":"holes must not contain null elements"}


Below is the stack trace from tomcat7-stderr.log. I would be grateful if someone can give a pointer to what I am doing wrong.
