node.js with Azure Storage TableQuery where colName like

I am using node.js with Azure sql. I am trying to do a simple search. I keep getting, "InvalidInput" : "One of the request inputs is not valid.".

function getItems(callback){
   var query = azure.TableQuery
     .select()
     .from('Employee')
     .where(['Email like ?', 'test%']);

  tableService.queryEntities(query, function(error, items){
    if(error == null){
       callback(items);
    }
  });
}
