MongoDB“无效的 BSON 字段名称”

Question

I know that there's probably a better way to do this however I'm completely stumped. I'm writing a Discord bot in which a user is able to add points to other users, however I can't figure out how to replace a user's "points". My code is as follows:

BasicDBObject cursor = new BasicDBObject();
        cursor.put(user.getAsMember().getId(), getMongoPoints(user.getAsMember()));
        if(cursor.containsKey(user.getAsMember().getId())) {
            Document old = new Document(user.getAsMember().getId(), getMongoPoints(user.getAsMember()));
            Document doc = new Document(user.getAsMember().getId(), getMongoPoints(user.getAsMember()) + Integer.parseInt(amount.getAsString()));
            collection.findOneAndUpdate(old, doc);
        }

My getMongoPoints function:

 public static int getMongoPoints(Member m) {
    ConnectionString connectionString = new ConnectionString("database");
    MongoClientSettings settings = MongoClientSettings.builder()
            .applyConnectionString(connectionString)
            .build();
    MongoClient mongoClient = MongoClients.create(settings);
    MongoDatabase database = mongoClient.getDatabase("SRU");
    MongoCollection<Document> collection = database.getCollection("points");
    DistinctIterable<Integer> docs = collection.distinct(m.getId(), Integer.class);
    MongoCursor<Integer> result = docs.iterator();
    return result.next();
}

I've tried findOneAndReplace, however that simply makes a new entry without deleting the old one. The error I receive is: Invalid BSON field name 262014495440896000

Everything else works, include writing to the database itself which is why I'm stumped. Any help would be greatly appreciated and I apologize if this is written poorly.

BSON field names must be string. From the spec:

Zero or more modified UTF-8 encoded characters followed by '\x00'. The (byte*) MUST NOT contain '\x00', hence it is not full UTF-8.

To use 262014495440896000 as a field name, convert it to string first.
