Recently upgraded to mongoose 4.0.2. The following code was working previously, but now results in the document being created but not passed to the callback:

Milestone.findOneAndUpdate({
    ......
}, {
    ......
}, {upsert: true}, function(err, res) {
    // err === null
    // res === null
    done(err, res);
});

This is only occurring on upsert . I can verify the document is created, but both err and res are consistently null. If I call the function again (now that the document exists) it works as expected.

mongoose: 4.0.2
node: v0.12.2
mongodb: 2.6.9

Use the new: true option, see 4.0 release notes notes on #2262 .

Milestone.findOneAndUpdate({
    ......
}, {
    ......
}, {upsert: true, 'new': true}, function(err, res) {
    // err === null
    // res === null
    done(err, res);
});
