Bad request sending GET request with id (ExpressJS)

node.js mongodb express mongoose mean

As MongoDB says that the default unique identifier generated as the primary key _id for a document is an ObjectId.

And it's 12-byte binary value which is often represented as a 24 character hex string.

And whenever MongoDB get less than 24 characters it does not accept that as _id. That's why you are getting some error from MongoDB side.
