Queries do not work in 2.0.1

We lately upgraded to GetEventStore 2.0.1 (from 1.0.1). No we face the problem that apparently the ad-hoc queries do not work any more, even very basic ones.
When we start the query it immediately stops with no error message. A sample would be



$init: function () {

return { count: 0 };


function(s, e) {

        s.count += 1;

return s;



in version 1.0.1 all our queries (even complex ones) worked just fine…

Are we missing something?

Did you have projections enabled in the previous version? If so did
you run the projections upgrade tool?

This is a brand new event store (no data migrated!)

Do you run with --run-projections=all
