  • @Neil Lunn ..Well, I got answer but it's still have problem. Could you help me? how can I fix it?` Error: Uncaught error: Argument passed in must be a single String of 12 byte s or a string of 24 hex characters at new ObjectID` – Kyaw Min Htwe May 16 '18 at 02:52
  • It's not an `ObjectID` is why, so my bad for presuming it was. `db.users` just looks wrong for a NodeJS API. Which driver are you using? Only something like mongoskin or similar have that syntax. The core driver would be `db.collection('users').findOne({ _id: +req.params.id })`. You probably just need the `+` though since it's numeric. If that at least works, then let me know and I'll switch the duplicate. If you still don't get a result, then please post "text" of your code and NOT screenshots, and I'll reopen to look at what your problem possibly could be. – Neil Lunn May 16 '18 at 03:09
  • @Neil Lunn Thanks Sir. wow..You're right. You saved my time. Thanks you very much again. It's work by adding `+`. I must learn more and more, I'm newbie in it. Here is what I'm doing.
