Regression in Sanity causing custom type preview issues

Hello! Just updated all sanity modules up to date using
sanity upgrade
and now a custom type I’ve made is not working out for me. The type looks like this:

export default {
    name: 'portals',
    type: 'array',
    of: [{type: 'string'}],
    initialValue: ['vt', 'vtna', 'vb', 'rt', 'udt'],
    options: {
      list: [
        {title: 'Trucks', value: 'vt'},
        {title: 'Trucks North America', value: 'vtna'},
        {title: 'Buses', value: 'vb'},
        {title: 'R Trucks', value: 'rt'},
        {title: 'U Trucks', value: 'udt'},
    validation: (Rule) => Rule.required(),
And I use this in another type under its fields:

        title: 'Portals',
        description: 'The portals in which this API should be available in',
        name: 'portals',
        type: 'portals',
And I have a preview using the portals type:

preview: {
    select: {
      title: 'apiName',
      portals: 'portals',
      id: '_id',
    prepare({title, portals, id}) {
      const subtitle = portals.join(", ").toUpperCase()
      const isDraft = id.substring(0,5) == 'draft' ? '👷' : '✅'
      return {
        title: title,
        subtitle: subtitle,
        media: <span style={{fontSize: '1rem'}}>{isDraft}</span>
The issue is that the portals variable is always undefined. Am I missing something? Thanks!

You’re not missing anything!
There was a regression with list options not being correctly rendered in previews, this has been fixed and should hopefully be out in the next studio release

Sweet! When will this release be out?

And is there a quick fix that one can use in the meantime?

Hi User! I’m not sure when it will be released, but the quick fix would be to either upgrade to the beta or downgrade
to a version before 2.13.
