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

In my case, this worked:

var myId = JSON.parse(req.body.id);
    collection.findOne({'_id': ObjectID(myId)}, function(error,doc) {
    if (error) {
      callback(error);
    } else {
       callback(null, doc);
    }
});

Don't forget to include at the beginning:

var ObjectId = require('mongodb').ObjectID;
