My mongodb collection has the following :

"_id" : ObjectId("589b04c2bc2f5a467c13303f")
}]
}
Can anybody help me please , thanks in advance ..
In mongoose you can do this -
CollectionInstance.findByIdAndUpdate(documentId, {
$pull: {
filename: {_id: urlId}
}
}, {new: true});
By documentId I mean 589b043abc2f5a467c13303b and by urlId I mean 589b043abc2f5a467c13303c in your above example code.
What we are doing here finding is the particular document in the collection through its _id and then pulling the particular document from the filename array through its _id.
The {new: true} option tells Mongo to return the updated document. By default this value is false and Mongo returns the document state before update.
