Mongoose: Cannot read property '$isSingleNested' of undefined

[pqvst]

I suspect this is an issue with mongoose.
I just upgraded from 4.4.2 to 4.5.9 and I get the following error:

info: ERROR IN RECEIVE MIDDLEWARE: TypeError: Cannot read property '$isSingleNested' of undefined

I believe my code that's causing the issue is:

Model.update({ _id: foo._id }, {
    $inc: { "foo.bar.rofl": count },
    $set: {
        "foo.bar.last_message": Date.now(),
        "foo.stix": err || "ok"
    }
}, err => done(err));

Any ideas?

Same error on 4.5.8:

4.5.7 works!

Same here, since 4.5.9 (4.5.8 is fine).
Having a look at the changelog, the culprit might be https://github.com/Automattic/mongoose/issues/4369

[emreeran]

Same here since 4.5.9
Happens only with $set of nested fields as the above

$set: { "foo.bar.last_message": Date.now(), "foo.stix": err || "ok" }

part

It seem to have been fixed in https://github.com/Automattic/mongoose/commit/658d6d0c55644f851c4022571c652a9128a61ed8
