Setter of watching attributes should be invoked in case of remove()

[zirkelc]

Hi,

I'm using the following two attributes to control the TTL on an item:

{
  expiresAt: {
    type: 'string',
    required: false,
  },

  ttl: {
    type: 'number',
    hidden: true,
    watch: ['expiresAt'],
    required: false,
    set: (_, { expiresAt }) => {
      if (!expiresAt) return -1;
      return DateTime.from(expiresAt).seconds();
    },
  }
}

Playground

Setting the expiresAt to an ISO string will implicitly set the ttl as unix timestamp. Now in case the I want to restore an item before it has expired, I need to set the expiresAt to an empty string in order to trigger the setter of ttl. I checked that .remove(['expiresAt']) will not trigger the setter.

Would it be possible to call the setter with an object like { expiresAt: undefined } to inform watching attributes that it was removed?
