Detecting and Correcting the ObjectID Error
I stumbled into this problem when trying to delete an item using mongoose and got the same error. After looking over the return string, I found there were some extra spaces inside the returned string which caused the error for me. So, I applied a few of the answers provided here to detect the erroneous id then remove the extra spaces from the string. Here is the code that worked for me to finally resolve the issue.
const mongoose = require("mongoose");
mongoose.set('useFindAndModify', false); //was set due to DeprecationWarning: Mongoose: `findOneAndUpdate()` and `findOneAndDelete()` without the `useFindAndModify`
app.post("/delete", function(req, res){
let checkedItem = req.body.deleteItem;
if (!mongoose.Types.ObjectId.isValid(checkedItem)) {
checkedItem = checkedItem.replace(/\s/g, '');
}
Item.findByIdAndRemove(checkedItem, function(err) {
if (!err) {
console.log("Successfully Deleted " + checkedItem);
res.redirect("/");
}
});
});
This worked for me and I assume if other items start to appear in the return string they can be removed in a similar way.
I hope this helps.
