I have the exact same issue as described in this thread (hence the similar title): Mongoose findOneAndUpdate -- updating an object inside an array of objects

Answer 1

I had the same problem, so I just delete $set from .findOneAndUpdate

Example:

function updateFood (userId) {
  SavedFoods.findOneAndUpdate(
    {
      id: userId,
      'list.id': 0
    },
    {
      {'list.$.name': 'Something else'}
    },
    null,
    (err) => {
      if (err) {
        console.log('Error:', err)
      } else {
        console.log('Updated', userId)
      }
      process.exit(0)
    }
  )
}

Works for me.
