“VersionError: No matching document found” error on Node.js/Mongoose

Question

I\'m relatively new to Node.js and Mongo/Mongoose, and I\'m having a very difficult time troubleshooting a specific Mongoose error:

VersionError: No

Answer 1

I had the same error when i tried to update a user's reference IDs to an email. The fix was really simple with async / await! Here the code snippet, hope it helps.

email
    .save()
    .then(() =>
      User.findById(email.from).then(async sender => { // declare function as async
        sender.emails.sent.push(email._id);
        await sender.save(); // wait for save() to complete before proceeding
      }).catch((err) => console.log(err))
    )
    .then(() =>
      User.findById(email.to).then(async receiver => { // same as above
        receiver.emails.received.push(email._id);
        await receiver.save(); // same as above
      }).catch((err) => console.log(err))
    )
    .then(() => res.status(200).json({ message: successMessage }))
    .catch(err => console.log(err));
