using simple await defer with Firebase callback throws error

[eladkarakuli]

I'm trying to wrap and sync Firebase query methods as follows

sync.fiber(function() {
            var ref = sync.await(spotsRef.once('value', sync.defer()));
            console.log("ref", ref);
            return ref;
        });

And I get this error:

/home/my-app/node_modules/synchronize/sync.js:111
        fiber.throwInto(err)
              ^
[object Object]

API for Firebase .once method

.once method like this? https://github.com/firebase/firebase-util/blob/d3a5b7d95/test/e2e/NormalizedCollection.e2e.js#L89

if that, i think you should change to this :)

sync.fiber(function() {
    var defer = sync.defer();
    spotsRef.once('value',
                  function(s) { defer(null, s); }, // success callback
                  defer);                          // failure callback
    var ref = sync.await();
    console.log('ref', ref);
    return ref;
});
