This fails:
update := bson.D{
{"$set", f},
{"$addToSet", bson.E{"outsideIp", "string"}},
}
updateResult, err := collection.UpdateOne(context.TODO(), filter, update)
This works:
update := bson.D{
{"$set", f},
}
updateResult, err := collection.UpdateOne(context.TODO(), filter, update)
Here is the error message:
multiple write errors: [\{write errors: [{Cannot apply $addToSet to non-array field. Field named 'key' has non-array type string}]}, \{<nil>}]
I only want to use $addToSet with a single string, as documented in the mongodb docs:
db.inventory.update( { _id: 1 }, { $addToSet: { tags: "accessories" } } )
What's going on here?
