Kendo Pivot Grid does not work with gte operator

Question

I created a kendo pivot grid , as in the example. I have the following options

$scope.options = { "dataSource": { "type": "xmla", "columns": [], "rows": [{ "name": ["[Date].[Hierarchy - QM]"], "expand": false }], "measures": [], "transport": { "connection": { "catalog": "EDI", "cube": "EDI" }, "read": { "url": "..../msmdpump.dll", "type": "POST", "dataType": "text", "contentType": "text/xml" } }, "filter": { "field": "[Date].[Hierarchy - QM]", "operator": "eq", "value": "new Date(2016, 1, 1)" }, "schema": { "type": "xmla" } } } 

and everything works fine. BUT, when I change the filter statement from 'eq' to 'gte' , I get the following error

Unable to read replace property from undefined
