Fetching items from a Meteor collection on the server throws Can't wait without Fiber

I'm making a fairly simple meteor app for the first time that is supposed to query all of the git issues from a certain repo. After it gets a list of issues from the github api, the idea is to create a collection of tasks from these issues. However, whenever I try to query the list of current tasks I get:

My first thought was that I was using a callback somewhere when I was supposed to be using a node-fiber, but the code seems relatively straightforward:

var repos = ['my-repo', 'my-repo-1',];

var pollGit = function() {



repos.forEach(function(repo) {

    github.issues.repoIssues({

        user: 'user',

        repo: repo

    }, function(err, stuff) {

        if (err) {

            throw err;

        }

        stuff.forEach(function (issue) {

            var sel = {git_id: issue.id};

            Tasks.find(sel).forEach(function (item) { //ERROR THROWN HERE

                console.log('got', item);

            });

        });

    });

 });

};



Meteor.startup(function() {

    pollGit();

});

This error occurs anytime I try and fetch the actual object after calling find. Just calling find() works fine. What exactly is causing the error?

Answering my own question in case anyone needs the answer:

Got it working with How to insert in Collection within a Fiber?

Code is as follows:

Fiber = Npm.require('fibers');

var repos = ['my-repo', 'my-repo-1',];

var pollGit = function() {

repos.forEach(function(repo) {

    github.issues.repoIssues({

        user: 'user',

        repo: repo

    }, function(err, stuff) {

        if (err) {

            throw err;

        }

        stuff.forEach(function (issue) {

            var sel = {git_id: issue.id};

            Fiber(function() {

                Tasks.find(sel).forEach(function (item) { //ERROR THROWN HERE

                    console.log('got', item);

                });

            }).run();



        });

    });

 });

};



Meteor.startup(function() {

    pollGit();

});
