Argument passed in must be a string of 24 hex characters - I think it is

Question

I have a method to find a document in my database based on its ObjectID:

      console.log(\'id: \' + id + \' type: \' + typeof id);
      collection.findOne         


        

Answer 1

Try this:

var hex = /[0-9A-Fa-f]{6}/g;
id = (hex.test(id))? ObjectId(id) : id;
collection.findOne({'_id':new ObjectID(id)}, function(error,doc) {
  if (error) {
    callback(error);
  } else {
    callback(null, doc);
  }
});
