Meteor Fiber error on upsert

help
1

I’m trying to run the following code but get the infamous ‘Meteor code must always run within a Fiber…’

Here’s the code:

     do {
        var addSubscriptions = Meteor.wrapAsync(
          sns.listSubscriptionsByTopic({NextToken: nextToken}, function (err, data) {
            debugger;
            if (err) console.log(err, err.stack); // an error occurred
            else {
              // call ListSubscriptionsByTopic again?  How?
              subscriptions = data.Subscriptions;

              // if (NextToken) {
              //   nextToken = NextToken;
              //   index = index + 1;
              // } else {
              //   nextToken = null;
              // }

              if (subscriptions) {
                var length = subscriptions.length;

                for (var i = 0; i < length; i++) {
                  var sub = subscriptions[i];
                  smsSubscriptions.upsert({endPoint: sub.Endpoint}, {
                    $set: {
                      endPoint: sub.Endpoint,
                      owner: sub.Owner,
                      subArn: sub.SubscriptionArn,
                      timeStamp: new Date()
                    }
                  });
                }
              }
            }
          })
        );
      }
      while (nextToken !== null);

Here’s my SO question on this.
