LokiJS - remove and findAndRemove do not work (saveDatabase not saving) - node.js

Question

I'm using LokiJS and it's fine for most parts. Except that I can't seem to delete a record from the database.
The find gets me the right record to delete, but neither remove() not findAndRemove() remove it after saveDatabase. What am I doing wrong?
(Note: I've tried saveDatabase outside the loadDatabase(...) callback - no change. whenever I re-run it, the record I thought I deleted is still there)
Here's the code: dbName is a valid path to the file
var db = new loki(dbName);
db.loadDatabase({}, function (e) {
var orders = db.getCollection("orders");
console.log(orders.count() + " orders found... iterating");
orders.find().forEach((v, i) => {
console.log(i + "." + v.key + " " + v.places.display + " " + v.theme + " " + moment(v.date).format("DD MMM YYYY HH:mm"));
});
}
let dKey = "some key that is valid";
if (!dKey) {
console.log("no key specified, returning");
return;
}
console.log("deleting specific record " + dKey);
let dObj = orders.find({ key: dKey });
if (!dObj || dObj.length == 0) {
console.log("no such record, returning");
return;
}
console.log(dObj[0]);
orders.remove(dObj[0]);
db.saveDatabase((e) => {
console.log("save complete");
});
}
});

Answer 1

Try: orders.chain().find({ key: dKey }).remove()

Answer 2

I faced the same issue while working with lokijs, so putting it here so that it can help anyone else looking for the same issue in future.
I was trying to lookup a record in db with a particular $loki value, but I was getting an empty ResultSet. Then I tried this.
data.chain().find({"$loki":{$aeq:serial}}).remove().data().
Here, data is my db instance and serial is the $loki value I was looking for and passing to find().
It seems like lokijs stores them as strings thats why $aeq worked and I was able to find and delete the required record
