Mongoose FindByIdAndUpdate Successfully Updates Document But Ruturns Error

findByIdAndUpdate() successfully updates document, but returns error which i don't understand. Here is schema: const userSchema = mongoose.Schema({ phone: String, password:

Solution 1:

The body parameter can be a Buffer object, a String, an object, or an Array.

For it to work properly, use string interpolation:

User.findByIdAndUpdate( result.id, { "token": Date.now() },
  (err, result) => {
    // It gives error, of which stacktrace i give below. But if check database - 
    // everything is fine, token was updated successfully
    if (err) return res.status(500).send(`Unable to create token. Error: ${err}`);
      return res.status(200).send(`${result._id}, ${result.token}`);
})
