Answer 1

I bumped into this issue some time ago and it also nearly drove me mad (oh, the joys of loosely-typed JS!). The problem is that you are trying to return an unacceptable type of data to client-side. Functions called via google.script.run have restrictions on what they can return (for example, you should avoid Date instances).

Restricted types

Currently, you can't return (take a look at the documentation for detailed explanation of restrictions):

1. Date instances;
2. Function;
3. DOM elements (though form is permitted);

Solution

Changing ary[1]= new Date(r[0]); to ary[1] = r[0]; should do the trick, simply move Date parsing to the client.
